Last night I used a DV-Mark FGC 121 at a rehearsal with a really loud drummer, and it kept up without difficultly. The amp weighs only about 22lbs/10kg, and was pretty satisfying to play. Sounded ok to me, but I don't really obsess about tone. I would be perfectly happy performing with it. I liked it better than the Fender Hot Rod I've used in the same room.
