My natural tendency is to want Beef Wellington, and I've sprung for it on a few occasions - HXDA, Custom 50, Smallbox, and the '66 Super (with the most excellent original CTS alnico speakers). Speaking of, I'm also a freak when it comes to speakers, I'll tinker all day to find the right match of speakers to amp, and I really believe it has taken some of my amps to that top level.
That said, I've seen some players use amps that I'll walk right past in a guitar shop, to excellent effect. Have seen guys use small Fender amps in pairs, Blues Juniors, or even a couple of the solid state Fender combos with a small effects suite, I think the Mustang II or Champ II, something like that. Or a single Hot Rod Deluxe. It keeps me grounded, not necessarily wanting those amps, but knowing that there's a validity to some of the more common, affordable amps. To that end, I've used several of the more affordable PRS amps to excellent effect. They fall under that umbrella, but they also reach up and grab much of the goodness from what would normally be a more expensive amp. PRS does a great job making their amps what I would call very natural and "honest" in their tone. Other affordable brands' amps play like they have bumpers on the bowling lane, it's almost hard to get the amp outside the sound they want for it, but that can make the tone more artificial sounding, too. PRS amps (IMO) can be less forgiving in the tone shaping sometimes, but the payoff is greater when I find "it," and that's what sets their more affordable amps apart. Not necessarily at that high level of the USA made amps, but they still put a big smile on my face when I play them. I enjoy a good burger, too!
