Lorbay is close, I do use a high speed dental type hand-piece. In my case, I use an NSK Presto. The two tools are pretty much identical in function, mine works more like a pen, but they fundamentally use the same 1/16" carbide burs at 300,000+ RPM.
I bet Lorbay got his from OneGoodTurn.ca I've never used that model, but Brian McEvoy has a good reputation for quality tools and videos.
I actually donated two pierced pieces and six conventional bowls which brought in a total of $2500 for the charity. I think this is probably way over market, which is unusual for charity auctions.
