I highly reccommend the Acoustic B200 combo. Although rated at 200 watts it will shake the foundation, and is very reliable. I bought mine from MF for $349 and it compares to amps costing much more. For extra security I bought the 4yr warranty for an extra $50. The sound is very clean without a lot of hiss or background noise. It weighs around 80lbs, so if you're okay with that, then it is a great amp. Oh yeah buy a set of casters it will make life much easier.
