I have found out that my dremel tool has died so I might need a replacement. Here's the scoop: I want to use it for removing some rust/loose paint on the car to repair. The dremel people suggest using a wire brush at low speed. I want to spend MINIMAL money. A single speed dremel tool is about $20 but this has only high speed. Multiple speed dremels are too expensive. A knock-off brand is maybe $10 or so. Chicago-something brand (?). Online comments state that this tool lacks torque. Maybe that is okay? Any thoughts or suggestions?
