Dell's U series monitors are all excellent. I've got a 2001FP in my cab, a 2005FPW in storage, a 2311 on my PC, and a 2711 as a second on my Mac. I'd buy any of their U series models sight unseen.
My greatest fear is that my 2001FP in my arcade cab fails. It's a 20" narrow-screen IPS display with a VESA mount... a very rare beast these days, and you need a much larger monitor in wide-screen to get the same kind of display height.
