I recently picked up a used Koch Studiotone head for $600. 20 watts, by far the best/most versatile amp I've owned, and both channels are very useable. I'm also amazed by how great it sounds at both bedroom and band volumes. I too play mostly clean or with light break up, though the lead channel scorches when I want more distortion. It also has spring reverb, an effects loop, direct out, all in a very compact/portable package. I have played a lot of the amps in this price range (Fender, Rivera, Mesa TA/F series, Vox, and Carvin), and for my needs, the Koch wins in every aspect.
