I really like the new cut off wheels for steel Dremel now sells too. They have only been on the market for a couple of years + -. They come in a thin version as well. And other models for wood and other materials use the same quick release system. As most people know I like to do carve blank lugs and these Dremel cut off wheels can hog out material quickly. Some of my frame building students hardly use a jewelry saw at all because most of the work can be done with these new wheels. The quick release system is vastly easier to use then the old screw system and of course the wheels don't break constantly, they just get smaller.

I have 2 newer Dremels and a couple of Foredom rotary units. One of the Dremels is a corded unit and the other one is battery operated. Since I am usually carving a fairly complex design, tool weight is important to me for fine control so I'm not wanting anything more powerful. In fact the corded Dremel is more powerful than the old ones I've had in the past. The battery operated one doesn't have nearly the power but its light weight and portability can be an advantage in some circumstances. The Foredoms are more awesome with lots of power in a small hand tool but the rotary shaft that drives it restricts movements in some ways too.
