Diki, my thought exactly! I just purchased a 3K, but the argument is the same. These are great machines that suffer from what I would call toy store design.

I don't know how many non-afficianado players purchase the upper level PSRs, but I would hazzard most buyers use them to play for an audience. If that's the case, then a stronger body and bigger keybed would be BIG improvements, in my eyes.
