30w is just about enough for anything short of a maniac drummer. Large venues will mic you, you could gig with a pod if you wanted. I've seen guys run into a laptop running sims before.
So, for $300, get something used with a quality clean, add a dirt box of choice, and you're done. Peavey Classic 30 or Valvemaster, Something from Laney or Traynor, the Jet City or Blackheart will all do fine, in addition to many others. Start with a Bad Monkey for dirt, they are a reasonable excuse for a Tubescreamer, and go used for $25-40. If you can run a soldering iron, the Crate V33/V18 can be modded into a dandy, and they go for next to nothing.
