I sold one for £2000 mid last year and one for $1500 a few months back. These were both really strong combos but were not pronouacable. I don't get involved with the lower quality cxz type combos because I see very little end user potential in them.
These were both end user sales. Reseller prices are much lower, obviously.

P.S. Happy to release the names I sold via PM, if interested.
