The Beall turning scraper?

[PTsideshow]

While reading the latest issue of the AAW's American woodturner. I found the ad for the modular tip scraper for mini beads and coves. They have 8 different profiles on 4 bits. It looks like a system that can be modified for any cutting profile by grinding HSS tool bits.
I am wondering what others think of them?

Expensive way to turn beads and coves, and depending upon wood may need lots of sanding after use.
