Sibling for LP2475?

[exploding5heep]

A friend of mine has an LP2475, and is now looking to buy another display. The computer is a Lenovo T61 and is used mostly for web browsing / coding. So far it seems that his options are a second 2475, a different 24 incher (U2410, zr24), or buy some extra hardware and get a pair of 2007fps. What do you all think would be best?

Bump? Has anyone been in a similar situation? The pair of 20s seems like a reasonable move, they line up with the 24 perfectly, and would give a nice symmetrical screen. The 2nd 24 gives a second "large" area though, and would be a higher quality panel. Advice?
