Your a great singer Donny (I have one of your CD's)...so why not just forget the foolishness & enjoy the 950...it is a great KB.
If you like the styles, features, sounds of the 900 better than make the switch..if not...why not just stay where you are.

As you know...right now I am trying the vA2 approach...we will see how it works out. (good so far).
