The Peavey IPS stuff is great, but a lot of people are looking at far eastern brands and doing very well. There's some brand beginning with W that keeps getting recommended all over the place. Obviously not enough because I can't remember the name. If weight isn't an issue then there are bargains to be had on ebay with old lead sleds. Everybody is downsizing, reap the rewards!
Crest, Crown, QSC, Peavey, Powersoft, Yamaha. They're the top-flight brands to various degrees.
