I really wouldn't compare the MZ-2000 with the PSR-2000.. When the MZ was released it real competition at the time was the PSR-740. I'm a former owner of the MZ and for a Casio keyboard it completely kicks butt.. I don't know why they don't continue to make more keyboards like it. The sounds were not the typical Casio sounds you hear on the CTK series or the WK series. The sounds were pretty damn good though... Some of the sax sounds were better than the Yamahas, and at the time the PSR-740's sequencer couldnt even be compared with the Casio MZ-2000.. The MZ-2000's sequencer however can be compared with the PSR-2000.. It does everything from step recording to event editing, track merging, copy, and a lot of other functions.. The arranger section on the MZ wasn't too bad.. You had room for 10 custom styels, and 20,000 notes to record styles.. The sequencer was 17 tracks and had room for 40,000 notes.. The only thing the MZ beats the PSR-2000 on is speakers, and that's it.. The MZ-2000 is 15 watts and boy is it loud too.. However I wouldn't compare the MZ-2000 with the PSR-2000.. The PSR-2000 is a more recent model for Yamaha and the MZ I believe was released 2 years ago. The PSR-2000 would be a much much much better choice than the MZ.. Also it depends on your budget too.. I've seen the MZ for dirt cheap.. At one time DanO had them going for I believe $650.00.., but if you want amazing features for the price take the PSR-2000.. It's Just over $1,000, but it performs and sounds like a more expensive keyboard...
