howdy.
if you do decide to buy new, also check out the prs se range, in particular
the prs se custom 24 if you're looking for a 24-fretter. you'll get a good range of tones out of that puppy, plus it's a good, value-for-money instrument new, but especially second-hand if you find a good one. the
se dave navarro signature (from what i've heard) is also something you might want to consider.
personally, i like to sit with the foibles of a guitar i'm attached to, and save up to buy another one that perfectly (or pretty close to perfectly) suits my other needs. welcome to the world of gas...
a superstrat is going to give you a very different sound to your epi. but hey, maybe that's just what you need! at any rate, get out there, play some new and different guitars and - most importantly - have a ball doing it!
