Good value Freesync monitor

Hey yinz,

I'm swapping out my GTX 970 with an R9 390 and I'm looking for a decent freesync monitor, preferably 1440p. Everything I've seen is either prohibitively expensive (>$700) or just has awful QC (a certain Asus monitor).

I was looking at this monitor but it's sold out at this point everywhere, which seemed like my best choice but is just unavailable. This also seems like a decent option

Any recommendations and experiences? I'd prefer to keep it under $400 but I don't really have a hard limit. And is perhaps waiting a few months until the new monitors come out worth it at all?
