After a few weeks with my "new" Em-2000, I am happy with it. It seems solid, I like its key feeling, and the sounds. I prefer this keybed to Yamahas, and some sounds (ex. piano). Yes, Yamaha may have a better O.S. (easier), better screen and a few better sounds (sweet ones), but I am not happy playing its small keys and, at all, sound from Roland seems fuller an richer to me.
The only pieces that seem not very solid are the five knobs below the display, and I want to preserve them... I use specially the knob to scroll through the zip drive or disquete files (the knob named bass/bank) for listening them. Is there another way to scroll them (ex. going to next style pushing some button and not rolling the knob (similar the way you may go up or down user programas with the two buttons dedicated to it). Perhaps with pads?
