All in fun Earl. The PSR 3000 was one of the very few Yamahas I didn't have.
I had a 2000, and used it for several years. Then I got the 2100, which had a few improvements, and I think was the first Yammy to have software OS.
I didn't get another Yamaha until S900, then S910, then S950, then S970. Each had just enough improvements to make you want to move up, but none were really significant until the S970.
Before the 2000, I had just about every Yamaha model from PSR6100 forward.
Before that were organs.
Also over the years I have had five Ketrons, five Rolands and five Korgs, some of them more than once.
I've now reached the point where I will NEVER buy another arranger. Unless they make something new.
