I've seen some of these on the used market. Are are new styles compatible with this keyboard? What do you think a fair price is? Any thoughts on this keyboard?

Thanks!

No new styles are not compatible but there are lot of old styles available for this keyboard. It's a great keyboard for the price.

Thanks Fran. What do you think a fair price for a used one would be?

Also for styles I need good Latin styles. Not ballroom dancing stuff. Salsa,cumbia, merengue, bachata, regaeton, and some regional Mexican.

In my country 250 a 300 Euro would be a fair price. You can find latin styles at http://www.korgpa.com/en/support/bonusware.html
Also at http://www.korgforums.com/?show=1 you can find alot of stuff for the PA50

My dad has the pa50sd. Very impressive sounding for a keyboard of this price.
The OS really is a headache though!

It's probably the most difficult OS I've come accross. Unless u have everything pre set in memory - forget about making changes and settings in realtime while playing!

But again it has alot of high end features that u wouldn't expect
