The RS 2000 came from the Stewart System which I've had since 1990 (won in a competition
As Mark has said it's basically a scraper system bur with a lot of handles. Just had a look at what it includes now and it looks like Sorby don't include the Arm Brace, the Omnitool or the Shear Scraper and IMHO it's not worth the money.
The best bit is the Slicer which when combined with the Arm Brace allows you to core any size bowl - last one I did was about 30 inches across.
John if you want to come over to my workshop I can show you the system and maybe suggest how you can achieve the same for less outlay.
