Anybody try one of those Rotozip/Dremel/DeWalt rotary cutters? Pretty easy to control and I've cut 20 gauge aluminum and even stainless steel with little effort. Also cuts circles in MDF speaker baffles pretty well. Did a head to head with the three: the Dewalt was more powerful, the Rotozip had the weakest motor but best circle jig and the Dremel was the tweener. Chose the Dremel. Gonna have at my 811B's AFTER I hear what they sound like in the baffles I'm building. Sometime in 2008.
