Not a bad find. I put in a lower offer we will see what I find out. No warranty is a big issue for only $100 less. But if they take my lowball it would be a lot sweeter...haha.
EDIT: they got back to me - best they can do is $850 FYI.

It's open box, there are 7 available from this seller (I bought one just now so only 6 available)... There is another seller which I suspect is of the same company...
