This is the original Yamaha S90:

It plays great, but needs to warm up and have the power turned on and off in the morning to get it going. Has a few cosmetic dings - nothing serious. I just had it cleaned and the dust blown out of it. Repair guy told me it could keep going for four or five years. Perfect for home studio use. Comes with a power cord; no pedal, no stand, no case.
