They're basically like the Korean panels on eBay. Just rebranded under the monoprice name.
At this price I'd buy it from them over eBay because they'd probably have better customer service and actually honor their warrenties.
This is disappointing. I work on a lot of apple computers, and whenever I see a 27" iMac or new apple thunderbolt display, I notice the beautiful colours, which are completely ruined by the flicker (from the backlight, I take it). I'll have to stick to my 85Hz CRT's until then. It doesn't give me a headache, but it is noticeable and annoying.
I have heard that some of the newer ones don't have the flicker issue that the apple cinema displays have, but I'd have to have some good evidence for this before I buy.
