I have a small Peavey Minx (2 actually), that is 35 watts with a 110, but I leave a Basic 112 at our practice site that I would suggest if it is your only amp ... two guitars with cubes, a piano with a Behringer and a drummer and it keeps up just fine .. not even cranking and usually with just one of my Squier Jazz's with Chromes ... very loud 60+ watts and you couldn't ask for more reliable ... I borrowed it out one time and it did a couple weekends for a keyboard player and came back with everything set on 10!! ... I paid $100 for it ... you can find TNT's, etc if you want more power, still under your $200 ... there have been some good reviews on here also for the new Acoustic brand combos, and I think you can get them in your price range ... I was in a local pawn shop (MN) last week and saw an Ampeg BA-210SP for $199, so there are good amps out there in your range, but again, better bang to buy used ... feel free to run what you see across here and you will get some good feedback ... JMHO
