After playing for two months (and lurking here for a week), I've got G.A.S! The little 15w fender practice amp I'm using is ok for practicing in my apartment, but my teacher wants me to start playing with other musicians soon, and I know I'm gonna need a better amp. After reading some of the posts here, it seems that ampeg, swr, eden, and carvin are really popular. Any other amps I should be looking at in my budget? I don't mind buying used, but I haven't found a lot of used amps in my area (NYC), and I'm weary of buying a used amp over the internet without seeing/hearing it first. You'd think that NYC would have a lot of used gear floating around, but I haven't found it. Maybe I'm just looking in the wrong places. Thanks.
