I want a head (I FINALLY SAVED ENOUGH!), so where should I buy it? Guitar Center has very limited section, and the local music store around here is the same way. My mom finally decided to let me get something online. What websites have lots of gear? New as well as used would be good. I think I'm gonna settle with a Hartke 3500 and then save up for a cab, probably Peavey. I know, the poor man's rig... Thanks.
