Hi All!
In light of the recent eBay 20% off deals, I have come across this monitor that seems to be the cheapest ($951.80 is the cheapest on Staticice as at 19/07/2016).
Seems to be a good contender against the ASUS ROG Swift however I don't have either monitors so best to look up your own reviews.
Use the code CTEC20 when checking out to apply the discount.

EDIT: As of 20/07/2016 17:25PM EST the listing appears to be out of stock.
This isn't an Xbox One
