I've had one for 5 years. Great amp. I'd also advise getting another cab to go with it eventually for bigger rooms.
I know a lot of folks say that you should never mix speaker sizes, but I pair a Traveler 115 with mine and I think it sounds great. Plus, you're taking advantage of the 500 watt head when you add the second cab. And if you don't want to "mix" sizes, just get another 210 cab.
