At those prices, I don't see how you could go wrong. I'm reading a bunch of negative crap about them, but it's all from people who've never tried one to start with. What a waste of words.
It's not going to be a high end Engl or Bogner, but it doesn't have to be. It just has to sound better than those amps we already know that sound bad, but sell for twice the price.
I have no problem with Behringer gear at all. I own some and have used other stuff and I have no complaints. I also wouldn't blink twice at shelling out some corn for a head and cab. Besides, if you get one and it really stinks (I doubt it), send it to me and I'll run it through the MONSTER-izer. The machine that cures all amp ills.
