My main amp is a GK MB212-II combo and I am very happy with it. The 2-12 setup gives me everything I want and the whole rig only weighs 41 pounds. I think the 12" is a perfect compromise of the low end of a 15" and the snap of a 10". I am a fan of the "modern" GK sound and this does that well, I am not sure how it would be if you are going for more of a vintage sound. The only gripe I could see is if you want an effects loop since this doesn't have one. I sometimes run an Pod Go before mine and do not miss the effects loop.
