Basically, I agree with Jed. Peavey 680D powered mixer with the requisite number of channels, both high and low impedance inputs. I swear by Bose 402 speakers which can comfortably handle small to largish size rooms and outdoor gigs. 2 speakers come in their own carrying case and weigh about 35 lbs total. Easily portable and really easy set-up and breakdown. I'll use 2 pairs for bigger venues. Ultimate speaker stands -1 per speaker. For monitors, I use little Boss powered monitors each with its own tone and volume conrols. They can be mounted on mic stands or left on the floor. Mic stands, and Shure SM58 mics.The whole shooting match easily fits in the trunk of a compact car.I've bought all my equipment on E-bay, used, at great prices.
