Regarding the keybed, it's not a piano. Personally, my arthritic fingers actually like the light touch. It's responsive, but in a different way from piano touch. It takes a totally different approach from piano keybed.
Wish the keys were a tad larger on PSRs though.
I find the keybed on PA3X really good and would probably suit most types of players. Of course it's about double in price.
