I use a Fender Blues Jr. Its just a 50watt(I think) tube amp with a 12" speaker. Its definately loud enough and with a few decent effects pedals you can get it metal, Hard Rock, Country, Blues, whatever. It doesnt have a very good frequency range though so your not gonna have it so bassy and loud that pants will be shat. Its just a cheap, decent, reliable tube amp. It retails at just under a grand NZ$ so i dunno what that is where you are. A lot less I'd imagine.
