I ordered a PCR800 just the other day and will see what it's like. It was $100 cheaper than A800.
I read reviews saying good thing about keyboard itself.
I tested some crap like M-Audio Axiom and was deeply unsatisfied with the key bed. Calling that semi-wheighted key is pure fraud IMO.
So that new stuff would be better regarding keybed I considered not to be automatic. I had better keybeds on Casio than this Axiom.
I had a Kurzweil with Fatar keys and also a Fatar VMK series but they are stinking heavy( and poor packaging from Fatar since it was broken and was sent back). And the worst with Fatar, it's Italian.
