I agree! It looks scratched in many places, doesn't even have the 14 bit better resolution of later models, it's dusty, and doesn't have a carrying case. All that for $7500 ? He's way off.
I've seen one that looked a whole lot better than this one (clean without any scratches), was a later model with 14 bits, and Kenton MIDI retrofitted, included a robust ATA case, all for $4500 not too long ago. That was more in the correct price range for all that. It didn't stay on eBay too long because it was a much better deal than this guy's.
There's always some moron on there that tries to sell at ridiculously inflated prices for synths in less-than-stellar shape. As soon as I see that someone is asking twice the normal value of a synth and doesn't even take 2 minutes of his time to at least remove the dust before taking close-up photos, I stay away.

Doesn't look too clean for 7500.00. Reflects in the blurb that "All functions work perfectly." I guess that's all that truly matters, but ....
