I've owned the keyboard for about three months. At least three times, I thought there was a bug that didn't really exist. The keyboard definitely has a few minor bugs (Well for a few people's specific style of playing these bugs are important), but there are some things like saving registrations and understanding the display, that some new to the PSR2000 just don't understand. There are a lot of threads with tips and explanations of how to do things on this keyboard.
Good luck Jedi with whatever you end up going with.
