It's a Rong Fu 45 or clone thereof. The power feed, stand, and vise are nice additions, but I'd take the description 'great condition' with a pinch of salt after looking at the pics and taking the seller's feedback into account.
The seller is obviously a dealer of some sort, and the mill has had some serious use.
It certainly hasn't been cared for and looked after in someone's home shop.
It may be in 'great condition', but only a careful personal inspection will ascertain that; 'caveat emptor' definitely applies in this particular case.
Bear in mind also that a brand new one can be bought from Wholesale Tool for $1.8K.
If it remains at $1K it might be a deal if it's in a better state than it appears.
