if you're planning on midiing stuff to a keyboard, the PA500 is possibly the better choice.
I have the PA800, & I've midied a couple of my keyboards/modules to it , (just to try). I would imagine the PA800 & PA500 would be similar in that respect.
I also tried something similar with my PSR1500, couldn't get the same result.
The midi functions aren't as good.

I'm a new member, and a newbee player, recently retired so now have time to learn to use the new toy, a Korg pa500, to add to an elderly Eminent 2000 home theater organ, and a Hammond ex1000 organ [midi in-out]. I tried to make a selection of a new keyboard based on input from others, and from demos, but finally I bit the bullet and rented for a month one kind, The Yamaha PSR s900.
I loved it's easy interface, amazing sounds and the great variety of styles. However I was bowled over by the Korg 'live' like sounds, and selected it. If you can rent both for a week or more, I think you will quickly identify what is better for you. My Renter would deduct some of the rent cost if I buy from them, so its not all loss.
