I got an email from Lee Valley showing this new plunge base for the rotary tools, like the Dremel. I see the basic kit is $85 and the complete kit is $169.

I know that there are other kits out there, but this seems to be of good quality while not being super expensive, like some of the other kits are.

Certainly going on to my wish list, I can see various project where this would be really handy to have.
