I picked up a new Rotozip yesterday. The plan was to use my aging Dremel to cut the mount for the Rotozip, but it bit the dust at the start of the top mount. I cut the rest by hand (pretty rough, but fits).
Although it's a bit noisier that the Dremel, it has loads more torque. I've gotta almost double my feed rate so I don't burn.
Pretty happy with it so far.
