whats wrong with epiphones?
That's my question too. Used Epi G-400s can be had for great prices and are fantastic guitars for the money.
Just about every manufacturer has an occasional lemon.
Lemons have a lot of bite, but some of the notes can be a little sour.
If it has to be new, I second (or however many it's up to by now) the PRS SE. Great guitar for the money. If you just want a new-to-you guitar and are on a $500 budget, though, I'd hit up places like Craigslist and Ebay, never know what you can land on there sometimes.
