Hi Herbi,
I know how you feel. when I bought my "Yamaha-PSR2000" there was nobody around my area that had one. The closest I got was a small music store that would "special-order" one but I could not return it.
So I went mail-order ,first time I had to reurn it. Then I waited a while and tried ordering again and it was "ok" (as ok as a y2k can be)
It is frustrating having to buy "sight-un-seen" !! I too would have loved the opportunity to try other KB`s but I owned "Yamaha KB`s" in the past so it wasn`t like a complete surprise!
The thing that helped alot was the ability to down-load the manual before and I listen to samples and the help I got here was the BEST
Best of luck with your KB search !!
