You should be able to score a Carvin XV-112 or similar on E-vil-Bay for around $350. You'll be getting an all tube, 100 watt 1x12 combo with a footswitchable
spring reverb & effects loop, a nice distortion channel and a superb clean channel. Considering all of the
solid state amps you mentioned, the Carvin will blow them all out of the water.
