What is your application? Are you looking to use it for video games or to watch movies?
If movies are your thing, remember, there are very few differences between a monitor and a TV. Grabbing a 3D ready TV and connecting it to your computer is equivalent to plugging it into your Blu-Ray player. The TV isn't picky, a video source is a video source.
Your only requirement would be to have HDMI out on your PC, as I don't believe DVI supports the standard.
If this is your application, then any 120Hz monitor will do the trick. These have been in stores before, but the series has progressed forward and I personally haven't seen them replaced.
