They make some good stuff but the more money they are the more likely a consumer power amp will be best. Big factor is fan noise. I did a little research and would probably go for the RMX 2450 or RMX 1850 HD if I went QSC but I would want to hear the fan before deciding. I would also look at Crown XLS and possibly Yamaha P-series before deciding. Like I said I wouldn't go pro unless I needed an enormous amount of watts for the money.
