The Behringer EP-2500 got good reviews by the "big boys" at prosoundweb. www.live-audio.comCan't beat the proce $/watt. Also heard good things about the Nady amps.
All of the lower cost pro amps are being built in China. I have a Crest and a Crown of Asian origin.
(got a BGW 500 on the stereo right now...)
