I'm happy with my Mackie M1400 (now only avail used --- eBay around $300). I ended up with it because I like the linear adjustable high pass (rumble) filter 10Hz to 170 Hz. I'm using it now bridged into 4 ohms. It is supposed to be capable of 1400 watts in that mode (I only "need" 1000)
BTW most pro amps need help quieting down their fans. I put a 130 ohm 5W resistor in series with the Mackie's 24 Vdc Panaflo fan and that did the trick for me. A lot of people have done a similar modification (100 ohm 10 watt rating) to Crown XLS pro amps.
