Hello-
I had back luck with my PA50 keys after a month of playing it. They loosened up quite a bit and I was extremely disappointed. You can download a lot of Korg styles for the 3000, but I found it very difficult to download styles to the Korg. Writing compositions is much easier on the 3000 and taking out instruments is a breeze. I like both instruments, but I'd give the edge to the 3000. This is an opinion only.
