Zuki,
If you loved the PSR2000, you will love the PF1000. Very similar operating system, some of the same sounds and styles, and some stunning additions. The action is fantastic, same as the Clavinovas. Overall, VERY nice! Keep the size/weight in mind if you're planning to take it to gigs. It's definitely a 2 man job. Hope that helps.
