Hello, the PF1000 is a great arranger with a digital-piano configuration, aldo it was based in the PSR 2000, so is a litte outdated as far goes styles, voices, still a very good value, I sold one last week, and so far, Yamaha has not released a replacement for that unit, I hope they do, is a good instrument and seller.
Other consideration could be the Roland KFseries, like the KF7....is a little different price area, but is an arranger and has an updated technology-features.
