Although there are many improvements on the "S" series , I wish I woulld have bought a new Y3K a few months ago when you could.

After reading all the reviews about the S900 , there was no mention about rubber buttons.

There was mention of "rubber like" buttons , but no acttuly came out and said " hey this thing has rubber buttons" !!

I have had many Yamaha`s in the past with rubber buttons and although they worked , my Y2K with hard plastic buttons was way better , not as far as sound , just as far as control.

I have been asking all over the place to try to find a "brand new sealed in box" Y3K and nothing except for eBay.
