If you want to look on Audiogon, you can look for an Acurus 3 channel amp. Can't remember the model number but it does 3 channels at 200 watts 8 ohms.
ATI also makes some nice amps as well. I have a ATI 1502 that's is 150 x 2 at 8 ohms (with another on the way) but you can run it in mono mode and it becomes a 450 watt 8 ohm monster. You might be able to find a ATI 1506 which is 6 channels at 150 watts 8 ohms or run it as 3 channels 450 watts into 8 ohms. I believe the outlaw amps are based on ATI technology.
