Behringer has been on a roll lately, and they now offer a 3 year warranty on many (all?) of their products. I recently purchased an XR18 digital mixer, and am really liking it.

I've read good reviews for several of their recently released powered speakers.

My choice of cheap and (at least) decent has been the Alto Professional Truesonic TS110A, a powered 10" P.A. / monitor speaker. I like it a lot, use it regularly, and am thinking of getting another for a matched set.
