Currently have the old 2407WFP. I was thinking about getting a second monitor to complement it, probably something around 20 inches that I'd stack in portrait mode next to it. However, in some basic google searching it seems like there are varying opinions and options, the 2001fp seems like a good suggestion, but I'd think that the brightness difference between the two would be pretty large. The 2007wfp is basically a smaller version of the 2407, but the pixel density is different. I'd ideally like something that matches the 1200 pixel height and is close to the same physical height. I've never done dual monitors before, so any insight is great. The card I have has a dvi, vga and hdmi port, so I am not sure I can even run duals without a new video card as well.
