How about the peavey valveking 112 Buy Peavey ValveKing 112 Combo Amp online at Musician's Friend it is a nice 50 watt tube amp with a low price if you need more than 50 watts there is also a 100 watt version the 212 and if you want a half stack they make a head and cabinent, but I imagine a 50 watt amp would be loud enough for most gigs.
