Hey Charlie,
In my limited experience, you can't beat Peavey. The XR series mixer/amp combo heads are proven performers. My XR-400 4CH is no longer in production, but it hit the road about 25 years ago and is still going strong. I still use it for small gigs and as a monitor mixer/amp.

Not sure what your budget is, but I'd pay a little extra and get something road-worthy and Peavey has a good reputation for value for your buck.
