I'm happy with the SX-900 keybed, I have had lots of different ones, from 1970's Thomas organ's to SX-900.....including a couple piano action synth's (Kurzweil) and all have been real nice. All of those instruments were higher end, so the keybed was always nice. The SX is my first PSR, and one reason I didn't have a previous one was the keybed was not what I was looking for.

Now, my big challenge is to find a 61 MIDI keyboard I can live with the action on for the lower. CME made the best, but they don't make them anymore.
