Not a bad price either.

For some reason, I keep getting a little twitch when I see these... not sure what it means. ;D
Picked up one recently on eBay for $430 shipped. Got really lucky and found the listing shortly after it was posted. At that price I couldn't pass it up.
That didn't last long. Sold already.
