Even though I've been here for a while, I've never really done any serious modding (I mostly just look at the pretty pictures ). I don't even own a dremel. Well, finally, I'm planning on starting my first project with a dremel and I need a suggestion on what to buy. I've never used a dremel before, so I probably don't need one of those fancy high-tech ones . Should I get a single-speed? two-speed? variable-speed? Do you have a particular model you could suggest? Thanks. P.S. I'm planning on cutting a couple of windows, so if anyone could suggest whats the best way to do so with a dremel.
