To be perfectly honest, after playing the PSR-3000, Tyros2, Tyros3, Audya and E80, all in the span of a week, there was not enough difference to warrant a decision based upon keybed feel. They were all pretty much the same, and none, thankfully, was nearly as heavy as a grand piano. One day, when I get some free time, I think I'll test the pressure required to trigger a note using a strain gauge or pressure point gauge. Should be interesting.
