Which arranger keyboard has the best quallity sound and style expansions?

And for what arranger keyboard is the best user created styles and sounds available?

Seems that for the Tyros they pretty much have their security in order making it prettymuch impossible to have illegal copies of the expansion packs, dont know about korg and Roland...

Audya audio styles are hard to find , which for me is one of the downsides.

The best third party for sounds comes for Korg pa ...If we are talking about styles,than Yamaha has the most.But,there is so much old stuff you can at least throw out at least half to garbage.Roland also has a lot of styles too.
