It is a big difference in warranty coverage, but the fact is that you could buy 8 channels of new Behringer amps every year for several years before you would equal the cost of say, an equally powered 7 channel Sunfire or Class D amp from D-Sonic or Wyred4sound. It's more hassle and risk than I'm personally willing to tolerate, but it's a pretty staggering statistic none the less. But for those willling to take that risk, the value is outstanding.
