It depends on what you plan to do with the keyboard. The PSR-2000 is a good board, but users are finding that it's not really suited for heavy performance. Its construction is not up to par with the PSR-9000. If you have the money for the PSR-9000 you won't regret getting it. The PSR-2000 is a cheaper alternative, but again the construction quality is no where near that of the PSR-9000. Also take into account that the PSR-9000 is a big keyboard and it has some weight to it. Of course you'll get more features with the 9000, but there are a lot of people out there who don't like the size and weight. That's why some have chosen the 2000. The 9000 has more poly, way better speakers, sampler, more mb's to the sounds, and a few other things. The 2000 is a great alternative to the 9000, but if you have the money I'd suggest getting the 9000...
