Hello
You may need to try both a little more. At first I preferred the PA80 over the PSR2000. BUT, the more I played them and pushed buttons I am glad I got the PSR2000.
For me anyway, the PSR2000 has much better voices except for possibly the organ. The jazz organ on the PA80 is quite good. But if you play with the buttons a bit on the 2000 you can get some real good organ sounds too, which I don't remember hearing on the PA80.
As far as key feel it took me a little while to get used to the PSR2000. Once I found the section to set the key touch the way I liked this made a big difference.
The PSR is far more user friendly. Try downloading and reading the owner's manual for the PA80, OUCH!!! About 300 pages that will definately keep you off the streets. If you don't like reading owners manuals as much as I don't consider the PSR2000. I figured most out just by pressing a few buttons and rarely looking in the manual.
Another idea check out a few forums for both instruments. This alone may help you make the decision. Go to the Yamaha section from the home page of SynthZone. Check out especially the PSR2000 Users site, and the Yamaha PSR styles group. The PSR2000 users site is the best. I know Korg has nothing like this. Then check out IrishActs which can be found by clicking on Korg on SynthZone home page. I found this stuff very hard to understand. I am more into making music than button pushing.
And even the video demos for the video manual for the PA80 was confusing.. One thing that they were showing, I don't remember what, but it was something that should have been relatively simple I found astounding. It said do this, then do that, then do this, then scroll over to page 13. and I knew this wasn't for me.
Maybe you are more of a computer head than me. If so the PA60/80 may be great for you.
The other idea I had for you is : you might want to get the Tyros which will be out soon. I probably will. It will for me just be an upgrade to my 2000 which I love.
I hope some of this helped. Remember, this is only my opion and experience. Try those boards out a lot before you buy. A lot of things people don't try until they get it home turns out to be suprizes. Anticipate what you are going to use it for and check as many features out as you can.
Good luck
