Hey, I've also just started, on the opposite side of the atlantic. personally, i'm about to go for a Fender Rumble 60, which seems a pretty good investment, although i can get it nice and cheap from a local shop, for £160 which is probably about $320. the best place to look is online, comparing prices and descriptions. just check everything atleast twice, and also check price. start off googling bass amp, find one you like, google the name, carry on right until you have name, picture, price etc, and everything else you need.
