I too went for the Double Cut as I didn't want just a better looking Les Paul - I wanted it to look like a PRS. I have not once regretted my decision either. Its such a great instrument and whilst I can't pick a 'favourite' (that's like picking a favourite child), I would certainly put it right up there with the 'best' of the best instruments. It really doesn't surprise me that John Mayer enthused about this model and rates it very highly.
Here's some Pic's of mine...
However, I was trying not to put my desires and feelings about which instrument I think is best when its better to try and get the OP to come to the right conclusion to suit their needs and budget. Its all well and good having a 'dream' guitar that is within their financial reach, albeit at the very limits of their budget, if when they do buy it, doesn't find it fits as well as they expected. Its like buying a GT40 and then finding its not comfortable or as enjoyable to drive when they do get an hour or two to take it out for a spin. They may have been better buying that Ford RS Focus as its more comfortable and fun to drive what ever the weather or surface thanks to its 4 wheel drive. Their 'dream' car of the GT40 just because of the looks and reviews rating it very highly, just doesn't 'fit' them or their needs, isn't very comfortable and the reality of ownership is not like the fantasy they had of owning one.
What I prefer, is to get people to try and come to their own conclusion about what is 'really' the best option for them, draw up their own conclusions etc. If that GT40 is the 'best' option, they may well know from going on a test drive, getting a feel of the handling and performance, seeing if its comfortable and going to be the 'best' 2hrs a week that they actually get to go out driving in it. It may well be their only opportunity in life to actually own that car too and because someone says that its not worth buying a car like that if it sits in a garage for 6fays a week, they end up buying a Ford Focus RS instead but just doesn't get them as excited to drive it, doesn't make them as happy or as enthusiastic to get in it, doesn't give them something to look forward to every day, maybe even become resentful because they had one opportunity to actually buy their 'dream' car but someone said it wouldn't be worth it for just 2hrs a week.
If I can get people to come to their own conclusion rather than impart my own desires or reflect my own situation, then hopefully they will make the right decision for themselves. If they get into that GT40 and it really excites them, makes them really happy and look forward to that 2hts of bliss every weekend, gets them through the week of drudgery, then its worth spending the money to get the GT40. They will know instantly if that is their 'dream' car from a test drive - even if its not the colour they prefer. They can order/find one in a colour they prefer, ask the dealer to get one in, and feel excited to get it and look forward to driving it every weekend. If they find its not the dream they thought it was, then they can reconsider, see if the cheaper Ford Focus RS suits them and their needs better. They won't be left wondering if they should of bought the GT40 either as they will know its not really what they wanted/needed despite the fact it looked like it maybe in all the video's they watched. They now have actual hands on and know how it feels to drive, how comfortable it really is etc.
Its not my money, not me that will end up driving their GT40 - even if I have a GT40 too and absolutely love it because maybe it suits me and my situation better than it does them - it could also suit them too of course. Its not me that would have to live with the Ford Focus RS which is still a great car and a lot of fun, its no GT40 though. Its not me that will be left wondering if they should have bought the GT40 but didn't when the only opportunity arose (you never know if another opportunity will present itself - even if there are more available - even 2nd hand). The only person fit to make the 'right' choice is the person buying. They know their situation and circumstances the best, they will know if the GT40 is their 'dream' car in reality when they get to test drive it, they will know if that will excite them, make them want to drive it at every opportunity, give them something to look forward to, whether its 'worth' the money to them regardless of whether I thought it was worth the extra. I don't want to be the person that tells them to blow all their budget on a car that doesn't excite them as much as it does me, doesn't feel as comfortable or as much fun as it does me. I also don't want to tell them to buy the Ford Focus RS and then they are left wondering 'what if', end up not being as excited or thrilled to drive as they could have been. If the GT40 is available to test drive, take it out and see if it really is the dream car for you or just aesthetically more pleasing.
I hope I have analogised well to illustrate my points. None of us are in the best place to tell someone else what to buy. The only person who can make that decision is the person who is parting money and having to live with that decision - especially if there is such a difference in price points. At best, we maybe in a position to explain the differences or to assist with any queries they may have. I want the purchaser to have no regrets or if they do, they only have themselves to blame. They can't blame me if they buy something that isn't the best option for them and their situation. I just hope that I have helped them to come to the best option for them without imparting any of my own bias.
