Really so, since I had ALL the key contacts all replaced. Good synth, good master keyboard also. Comes with good skb case, and 3 rom cards. I can throw in sysex d50 software and downloadable sounds are unlimited with the web. Manual with D50. No smoke since contacts replaced, so they'll last quite a while yet. Trying to avoid Spam-Bay if I can. Also selling Yamaha TX 7, nice when midi-ed to the Roland. No manual, but surely available somewhere on the web. Both for $500, nice if you can come try it out and pick it up. In Western Md, USA. Also will part with working Casio CZ1000, excellent condition. I used it for bass. Throw in cartridge and manual. Gee, I can sell my Roland TR505 drum pattern player as well. Best when used as midi device, but still working well. Looking for hard disk recorder, and small but very effective high quality PA system. (Bose? JBL?)
