Oops, I hit the submit button by mistake. To finish, my first Dremel was the Mini Mite cordless
http://mdm.boschwebservices.com/MDMC...0/r00014v2.jpg. When that bit the dust I got the 7.2 Multipro cordless
http://mdm.boschwebservices.com/MDMC...0/r00013v2.jpg which is just a little more powerful. I also have the 300 variable speed tool, but I prefer the cordless for nails.
I use a sanding drum like

You have to be VERY careful not to get either your's or your baby's longer hair caught in the Dremel. It might have to be cut if you do in order to get it untangled, and I speak from experience (my hair).
