For the 2000 CU24 - at $1100 OBO I would probably jump on it depending upon neck shape, color, and how bad the dings are. If it has a 10 Top, the OHSC and docs then even better. But for that price, if the guitar speaks to you then you will be hard pressed to find anything better no matter the aforementioned criteria. Heck, if I could move some of my extra gear fast enough I would probably jump on that.
As for the 30th Anny goes, well, again, neck shape, color, and how it feels in your hands. I'm not going to quote a price (EBay sold listings will help you figure that out) but I will say, after playing on my buddies, these are sweet guitars as well. Since this is a relatively new model, where you live will impact the price (for example, from experience the North East corridor has a plethora of used PRSi so the prices tend to be lower there compared to the Midwest). With everything included, I would surmise a guesstimate at between 2 and 3K. More if its a 10 Top with an Artist package. Again, it all comes down to how it feels when you are playing it and what you're willing to spend.
More details, pics (because we like seeing guitar pics!), and other info can help us get you a better idea of things.
