And here's my two cents from a dealer's prospective......
What I haven't heard anyone else post is that the 2000 actually has better styles than the PSR9000. The session styles (some of the new ones) are not in the 9000 and they can't be loaded in because the 9000 wasn't made to accept this new extension type. Also, the sequencer in the 2000 is just like that found in the 9000, so for composing, you have a major upgrade over the 740's rather lacking sequencer. Except for the acoustic piano in the 9000pro, the sounds are pretty much the same in the 9000 and the 2000. Unless you need a hard drive, using the 2000 is great for playing styles from disk and playing midifiles from disk. It is also faster and easier to record songs when you need to quickly. I won't argue with the fact that the psr9000 is built more heavy duty, however most custsomers will be very satisfied with the 2000 for most situations.
