While I generally deplore the endless behringer argument, I'm going to jump in here. Being broke and cheap (frugal?). I've purchased and used a fair amount of behringer gear. I've found that for the money, the amplifiers are just ok. Poor construction, failures, etc...
I've learned that it's a better idea to save up a few extra dollars and go for a used GK or Hartke. Hartke stuff is very reasonably priced and built like a goddamn tank. It can be run hard, slammed with distortion pedals and cranked to full without breaking a sweat. Also, Larry is the best and their customer service is top-notch. I think the same can be said to a lesser extent for GK.
So I tend to avoid active electronics from Behringer. However, I've been using two of their (discontinued) BB115 cabinets for 6 years now. They sound great, and have taken a beating without any issues whatsoever. The drivers are rated at 600W, which I used to think was ridiculous, but I've been slamming two of them wired in parallel with 1000W amplifiers and they're standing up to the abuse just fine.
I'm not a behringer basher by any means, I still own and use a lot of their gear, but I think there's better amplifiers in that price range, especially if you go used.
My $.02...
