Nobby,
The PSr8000 is discontinued . Yes you may find a few in a store or mail order "new" .
I did have a chance to play the PSR2000 at summer NAMM (nashville) . It's going to be a nice keyboard . Better than PSR8000 . No question . I would wait to see the 2000 .
If anyone is interested I do have a PSR740 available used for $699.99 . Perfect condition . I like the multi pad feature better on the PSR74O . However the PSR2000 was only prototype when I played it . The multipads were different in the PSR2000 vs. the 740 , 640 .
If you compare the PSR550 to the PSR540 you will find taht the multipads are better on the PSR540 in my opinion .
