Choice of Korean Monitor Help Wanted

http://stores.ebay.co.uk/Dream-Seller/WQHD-2560-x-1440-/_i.html?rt=nc&_fsub=6547849015&_sid=1067141085&_trksid=p4634.c0.m14&_sop=15&_sc=1
The monitors on there would be awesome to get as they are basically cheap as chips and give lots of features for the price, whereas over in the UK i could pay double that for the same panel...
What is the best one to get for screen quality/response time for gaming? Also what resolution, if you scroll down the side you can choose:
FULL HD [1920 x 1080] (9)
WQHD [2560 x 1440] (29)
WQXGA [2560 x 1600] (6)
UHD [3840 x 2160] (3)

And i have a Sapphire R9 290 to power it so should be enough for all the top 3 choices...
Just drop me a recommendation and is it worth paying the extra £30 or so for perfect pixel?
Also What about this one, as i love the look of the widescreen monitors:

Looking to spend absolute max £250, the cheaper the better really

they are korean monitors, they are the 'big thing' as you can get a high end monitor, just with a different housing... but there is risk, ie, monitor arriving with dead pixels, ridiculous light bleeding etc... but if you get a perfect pixel one, they arent bad at all... for the cost aswell, its amazing!
