Where to get styles for E80 (totally new to me)

Got a demo of the Roland E80 and now in love with it. Guy in shop is trying to sell me few thousand styles he has on flash card memory. He said he has been getting them saved up over a few years...? Anyway, is there a way of getting these to download and is done onto a flashmemory card? Also how do you get the styles onto this. And do they just stick into the back of the keyboard? Sorry - lots of questions there, any help appreciated.

Thanks

I bought some Christmas styles from Midispot and put them on a 1.0 gig compact flash which fits in the slot on the back with a pc card adapter. Then on the keyboard, select style under "finder" - then on the screen select external memory and they come up. I haven't been able to find too much in the way of freebies to download. If anyone knows of where to get some styles I would be interested too.
