I've been on the hunt for monitors for a few weeks and even now, I still don't understand why some are priced such significantly with similar specs, e.g. Q27q-10 $359.20, P27q-20 $527.20, specs comparison looks near identical.
Anyway, this looks like a good deal to me, 27 inch QHD so should be sufficient good to look at, released mid August last year, so still pretty new

They also have height adjustment and can be rotated into Portrait orientation.
