I don't know about the 30", but the 27" "Glass Pro" version got a glowing review from Anandtech.
Seems like the general consensus right now is that there are not any really good all round 30" monitors being made. All current models have some type of problem or multiple problems. It was hoped the Dell U3014 would be the one to buy but its got problems too. Right now its 27" or go TV as best options. Hopefully in 2014 Dell and others will come up with good 30" models. The focus however seems to be more on 4k which will be much more expensive. Personally, I would hold off on a 30" and wait to see what next year brings us. If you want something now get a 27".
