IMHO, you should keep buying combos until you have an amp at every trustworthy location, to cut down, or eliminate carrying those heavy little SOBs. My last purchase was a PV TKO 115/80w for 80 bucks, and I leave it my bud's studio. At that price, if it walks away (which it won't), it's not the end of the world...PS, two or more stacked make a very respectable amount of sound, modularism at it's best...
