Hmm. Good solid state combos? Tech-21. For what you get, the price is VERY reasonable... If you know you'll have a mic, an available channel, and enough power fromt he PA to get it up to manageable levels, the trademark-10 is about the best sounding small combo I've ever heard. If not, I'd say pass over the 60 and go for the 120- the 60 is GREAT for cleans and medium-gain tones, but for heavier stuff, I couldn't quite get a sound i liked out of it. I actually found that I got better sounds by distorting the "clean", fender-y channel and setting the darker "distortion" channel for a clean tone- it never got perfectly clean, something about enguaging the boost circuit (forgot what tech21 calls it, but that's it's basic function) on the fender side gave a slight grain-iness to the other channel- you could hear the difference on the marshall/mesa channel if you clicked back and forth between the boost on the fender channel- but it was serviceable. the trademark-120, however, had a bit more power on tap and was basically like three of the trademark 10's run paralell, with a few more options on tap- it could give you three independant channels with just about every concievable gain style and level on tap. Besides, it'll probably weight significantly less than any similar tube amp...
For solid state gear, Tech-21 isn't cheap, but you get what you pay for.
If you're willing to spend a little extra cash, you could definately find a good low-wattage tube amp that would also give you the kind of power and tone you'd need- the two I always suggest are the Mesa Nomad-45 and the Marshall DSL-401. Used you can probably find them around $600, about what you'd be looking for the tech 21 trademark 120, i believe, and tubes just have this magical character to them... A good tube amp running hard is a thing of beauty, and if nothing else, the psychological benefit of "heeeeey... my amp has little glowing things inside it!" can't be overlooked.
