I just talked to the Ketron Rep in Texas. He is bringing a Vega and SD1 for me to try out. Also the Tyros should arrive at my dealer's store in the next few days. (So that I will be able to eliminate it from consideration, I hope).
You know, I've had this 2000 for over a year, which may set a record for me. I only got it as an interim keyboard. I like it more and more.
