Crown Hollowing Tool

[BC in CT]

I am looking at the Crown HTC1 Hollower/Scraper tool for turning some small to medium forms such as potpourri bowls, small vessels, etc.  The shaft is half round, with a flat on one side to counteract torque, and comes with three different cutters.

These have been around for a while but I have been unable to find any type of reviews on them so I was wondering if anyone here has any experience with them.
Thanks, Brian

Another option I've been looking at is the Sorby RS200kt hollowing tool.

Anyone have experience with this tool?

Thanks,
