I have said this many times...I love the feel of the PSR's keybed...in fact, I prefer it over the Tyros...it works perfect for my needs...light, fast, and accurate.
I have a digital piano if that's what I want to play...the PSR series are unashamedly arrangers...and they do the job quite well for pros as well as amateurs or home players.
Key feel is very subjective and personal; so you will have many differing opinions.
I've never played a Korg arranger...they won't carry them in my area; but I have heard great things about the PA-800 from Uncle Dave and Zuki, and they are pros, so it must be pretty good.
Wow! $9000 for an Audya...and it's not even finished yet!
