I think you got the facts right...The PA800 was so overpriced,(Not unlike the Tyros4).. they lowered the PA series (600) to ease the cost pain a bit...problem is,,all of these keyboards are incorporating compromise..From the BK to the PA and PSR.

I will reserve my decisions until I play all the sub $2500 keyboards..But visually it is evident..cheap is the common feature...and I am not talking price...but quality built..

Am I the only one that feels this way?
Don't you guys like the feel of a real instrument under your fingers?

To me , they are all making entry level keyboards, with some nice features..but are screaming "Home" use...they should put "fragile" do not move on the name plates..
