I am going to second the Bugera route, except I am going to suggest the 333xl 2-12 combo. You should be able to walk out of the store at about 500+tax. It's an all-tube 3 channel MONSTER of an amp. Sparkling clean channel, nice overdrive, and then a monster lead channel. The power tubes are interchangable too, (but I wouldn't suggest doing it yourself without knowing what you are doing).
It's also got a built in noise gate and digital reverb. OH did I mention it's 120 watts of ALL TUBE MAYHEM????? I bought one of the first ones to come off the line, and it's been worth every penny of what I paid. Countless gigs, and never let me down yet. It's actually a Soldano SLO-100 clone, so you get the nice gritty Marshall sound also.

It comes packed with EL34 tubes and you can change to the 6L6's for more of modern rock sound.
