I own a PSR2000 and a Kurzweil pc88. The latter has a great 88 hamer action keyboard. The former has great sounds and a lot of options. At home, I almost never actually play on de Y2k. I use midi so I can play on de pc88 and listen to the Y2k. For me this is a great combination, The sturdiness of the Kurzweil and the options (sequencer, sounds, etc) of the Y2k. At smaller gigs I only bring the Y2k. For more important things I bring them both. This way I have the best of both worlds.
