I believe the keyboard 'bounce' comes from the stand, particularly if you use an X type stand. I notice little (if any at all) bounce when I place my keyboard on my Quick Lok brand Monolith stand . . .

and I've even been known to give the 2000's plasticy toy keys on the PSR2000 quite a workout . . . . yet . . . this kb keeps on going , just like that Duracell bunny.

At this point, it seems like the Tyros is the best kb upgrade option for me right now, otherwise stick with the PSR2000 till the next arranger keyboard offering. I'll audition the Tyros (if and when it finally arrives) and make a final decide then. The Technics KN7000 is a built in speaker possibility but the cheezy vocalizer, inconvenient drum fill to variation, weak drums, and poor split mode jazz chord recognition are keeping me luke warm about goig that route. On the other hand, playing the KN7000 jazz & swing styles in full keyboard mode is a total JOY! I especialy like the KN7000 Steinway piano sample.
