Jose,

Probably the best place to find users demos for PA800/PA2x is korgforums.com.

PIANOS: If you don't like the stock pianos in the PA2x or the ones from Irish Acts, then in the forum, if you do a search you will find out that many users have publish a variety of piano samples FREE. If you still can't find one that you like it, then you better look for another arranger brand.

STYLES: The PA800/PA2x have very good styles. I am from Latin America and I think that ALL the arrangers have incomplete offerings for Latin music, but take in account that is no easy task. The cuban Salsa is no the same that the one from Puerto Rico, The same can be said about merengues, cumbia, bachata, etc.
The best solution for me is to take the styles for the gen that I am interested from different arrangers, convert it to the one that I own and then modify it at you taste.

The site createsongsstyles.com have a lot of offerings on styles and sounds too.

I think that some times we make to much emphasis in the keyboard. My experience is that the key is the player. Many players in this forum have been able to demo nice sons with no top of the line or the latest arrangers.

I like Korg PA800/PA2x for the sounds, of course, but for other features too:

- Songbook (best of any arranger)
- Interface
- Easy to mute style parts
- Import of samples (sounds) from third parties
