Dude...if you're gonna go Crate, you have to take a look at the Blue Voodoo head. I think it was probably the only good guitar head they ever made. It's all tube and it has a pretty sweet sound. The guitar players from Asia used it exclusively for a long time around 2 or 3 years ago (they had them when I saw them with Peter Frampton, Nightranger, and Styx). I can't think of anyone else off the top of my head.
You might want to take a look at a used Randall, or maybe even a Polytone so that you can have a really clean amp and rely on pedals for the distortion. Polytones have a great crisp sound to start with. They can make just about any pedal sound amazing and crystal clear.
