I've got an off-lease P1110. Very nice monitor - crystal clear image, excellent geometry, good colour. Hook it up to a card with really good 2D quality (Matrox, ATI) and it'll shine even at 1880*1400. The sharpness of the image puts any LCD I've seen in my local big-box stores to shame.
I wouldn't get one on eBay though, since it'll be refurbished you want to see before you buy. There might be damage to the anti-reflective coating. Some heavily used Trinitron tubes also have brightness issues. Also be aware that it does have those two hair-thin lines across the screen (tensioning wires) common to aperture-grill screens. It doesn't bother me, but some people hate it.
