Technics KN2600 looks good, especially doing away with the floppy drive and allowing digital audio out via USB. However, it does not appear to have a harmonizer (and if it did, I'd want to check it out first, as Technics attemts hat vocal harmony have not been great in the past), so if this is important to you, better wait for more definitive set of information.

EKO is also out of this category - check prices on their web site. It is like building a house - the base price is around $2000, but that buys you only an overpriced PC in a funky case. By the time you add all the important components, like screen, a pushbutton button panel, a slider panel, etc., be prepared to pay twice that much. Plus figure the cost of the software on top of that. Besides, it appears to still be vaporware - an interesting concept which has not yet come to fruition.

I would concur with part of UD's statement, that at this time PSR2000 is in a class by itself. What it lacks in sturdiness and expandability, it more than makes up in the very complete set of features, sounds, and the polished OS. In this it has a solid edge, IMHO, over the Rolands, Korgs, and Ketrons in the similar price bracket. I suspect that even the "low-priced" Technics will be almost twice as expensive as the PSR2000 is today.
