There were no less than 2 of them at the Nashville gun show this past weekend. On Saturday the prices were $650 & $649.99. On Sunday, the first dealer dropped his price to $625. His shop is right down the street from my apartment and IIRC, he's had it sitting there for two or three weeks.
They definitly look like something out of Star Wars. From what I saw, they seem pretty decent though. Maybe someday.
