I'm currently using the Behringer PMH880S with a 4-piece group and with solo gigs. I love this compact, light-weight unit. No problems, as yet. And now, at NAMM '07, they've shown the new PMP 1280S at 1200 watts. Price expected at $499.99. http://www.behringer.com/01_news/events_namm07.cfm?lang=ENG
