Tough question to answer. I will say this. I just bought another Peavey Valveking 100w 1/2 stack. You can pick these up on craigslist rather cheap. I payed $550 for mine and in perfect shape.

They are a good amp and with a little tweaking can be turned into an excellent amp. http://www.peavey.com/products/ValveKing/index.cfm . Not sure you would want a 1/2 stack or not. If not, but you like the tone of the VKs, they do have smaller versions as you can see on that link I just posted.
