I'm just as bad with Bosch 12V, though I have a couple DeWalt 12V tools (the inspection camera, flashlight, IR thermometer and a 3/8" impact wrench) and Milwaukee (Hackzall, MSpector, palm nailer and the rotary "dremel" tool). I am on my third rotary tool, and I have only used it once. First one smoked when I turned it on, the second did not work at all, and the current one is fine other than the bearings sound like ****. We'll see how it works out. I do like the power of the rotary tool compared to my 10.8V Dremel (no comparison, really, the M is twice the tool). I am awaiting the release of the ratchets. I use a Skil 7.2V 1/4 incher for auto work, as do my shop-mates. The Skil, while nice for light work, has a design flaw with the battery power monitoring circuitry that cuts the tool off prematurely. It has never been updated or released as a new model, and there is nothing decent IMO as a replacement. The M12 versions should be fantastic, though a bit larger overall.
