I am not UD but I will try to make his job easier.

It is basically a Yamaha PSR2000 (all the layouts the same but with the improved sounds of PSR3000/Tyros) AND with better keybed like the KORG PA80, CASIO WK3000 instead of the mushy keys of PSR2000. And an internal HD.

THAT I think will make the man a happy performer. Right UD ?
