Check the reviews on the P800 in the Lula Home site. It may well make you lean for that printer.
I had to replace a 2400 last year (it replaced a 2200 before that). I also have a 24" P6000, so I did not really need the 17" capability of the P800 but since the P800 is barely larger than the 2400 and can sit on the same base I have for it, and the other advantages over the P600, plus the rather small price difference over the P600, getting the P800 was a no-brainer. I use it daly and it is working perfectly. As I mentioned in another thread, if I had to keep only one printer, I would let go the 24" one and keep the P800.
