I have the S2309W which I paid $250 for just six weeks ago, and I like it. It's hooked up to a unibody MacBook via the mini-display port/DVI adapter, and it works well. I'm color blind, so I'm not the best judge of that, but it's nice and bright, and all the vids I've played on it looks great.
If the S2409W was to be had for $250, I would have picked that one up instead. Ah well, I guess an extra inch or so doesn't matter that much.
