Had one for about 6 years, really enjoyed it. For sure this synth is the KING of silky string pads. I had a lot of fun using it as a controller for CS-80V (using MIDI translation software to convert the Sysex code into CC's). I also did some restoration on the keybed (removed the red glue, installed a new contact strip under the keybed to replace the glue-ruined one). Alas I had to sell it last year (and I need to change my sig gear-list to reflect this, of course), but it is a highly recommended synth. For a digital, it is quite capable of sounding analog. Some of the best digital resonant filters ever made.
If you don't need the control surface or the keybed, and would like more synth power under the hood, the JD990 rackmount is the one to get. Has a lot more synth features (like osc sync, osc cross-mod, etc.) that are missing on the 800.
