lg W3000H, its the only recent 30" that doesn't have a scaler (which causes the lag) the dell 3008 uses the same panel but adds a scaler. Think the dell 3007 didn't have one but is an older panel now. Had mine a few months now and loving it, though its hard to find reviews.
you get square eyes on that size monitor why on earth 30" lol i used to play on a 32" sammy and it did my eyes in now play on 22" happy as larry and i only sit half a foot away.
half a foot? as in 6 inchs? need glasses much? most people sit 30cm away or so. i sit 2 & 1/2 foot away from my 24!
