I had a 3014 at work and I stopped using it because it was terrible with Mac OS X. It had this thing where it would blue tint a box around any sustained motion on the screen, like a video being played. It also came out of the box blue tinted and with the sharpness cranked up. So while the Seido might not be great, the 3014 is no panacea either.
There's some hacking that has to go on at the OS level with OSX to have any monitor > 27 inches. The trouble lies in that the operating system wants to natively believe that you're actually using a TV, not a monitor.
