I think you should consider the Behringer PMP518M. It's a 5-channel rackmount unit. It was selling for under $200. Add a pair of Peavey PR12 speakers for $340 (or PR10 @ $300) and you've got a powerful, dynamite, lightweight, portable setup at less cost. http://www.behringer.com/PMP518M/index.cfm?lang=ENG
