Hi Marcos,


I am a owner of the PSR 9000. Unfortunatelly I played PSR 8000 too shortly and I cannot give you good comparision of these two keyboards. But, if you want to experience something about differences in features of both keybopards, go to: http://www.yamaha.co.jp/english/product/pk/nonflash/products/psr9000/psr9000.htm
and click 9000 vs 8000. It is very good comparision chart.

I do not know the prices in Brazil, but in Germany you can get a new PSR 8000 with HD and 32 MB RAM for 3,880 DEM (2,047 USD). Therefore I think, your friend's price is too high (for 2,400 USD you can get new PSR 9000). If you want to know more about PSR 9000, read the owners's comments or go to: http://www.keyboards.bizland.com
