I get that for sure, though I only have one guitar I own that I actually played before I bought it. I stopped in a GC about 6 or 7 years ago and fell in love with a budget Schecter CR-6 that just hit exactly what I needed. I still have it, it's a unique and fun guitar.
Generally speaking, I either buy new, or if I buy used, it's a vintage Ibanez, and I know Ibanez so well now I know exactly what to look for in a listing to know if it's for me or not. So I'm either buying a new guitar with a return window and then I'm only out the return shipping, or I'm getting a unique vintage Ibanez that really slays or needs some minor work to bring it up to my playing needs.
Of course this would be solved if there was a local music store that stocked high-end guitars that don't say Fender or Gibson on the headstock. I don't know any place locally that would have Ibanez Prestige, USA Jackson, or ESP E-IIs.
