Suggestions for used 4k IPS monitors for design work for cMP?

[absente]

My cMP is finally coming to live and I am looking to get nice monitor for it. I am doing mainly graphic design / rendering / color work, so that's why I recon IPS would be the better choice. I am NOT gaming, so response time is not an issue for me.

I want to pick up a used monitor, 27" under $500. Currently have my eyes on the Dell P2715Q which seems like a nice 4k monitor within my price range and offering full resolution at 60Hz.

I am currently typing this on a 2013 27" iMac, but it's really terrible for color grading, color spaces etc. I'll use a Geforce GTX Titan 12G.

Any recommendations for some good used 4k monitors that fit my requirements?

I got a Dell UltraSharp U2713HM 27 for £175 from ebay to use with my 5,1 2010 Mac Pro. Not 4k but it is an IPS panel, calibrates OK and is a good size. I think the newer models of the Ultrasharps and presumably the 4k Dells will be good bang for buck.
I do print graphic design and photo editing. Eventually I'll upgrade to an NEC Spectraview and a new Mac.
I find retina type screens aren't perfect for photo editing if you need to see actual pixels due to the zoom factor (100% in Photoshop is too small, 200% you are interpolating), but they do look great!
When I was in house it was all Eizos, but they weren't 4k.

P2715Q is an excellent monitor. Using one right now!

This is great info, thanks. My Dell is right in the non-Retina sweetspot.
