heya all, i'm looking to buy a new dremel for all my modding/building projects, and i can't decide which one to get. I don't have a whole lot of cash, so cheaper, the better. I was looking at one with a rechargeable battery and 2 speed settings (5k and 10k), but i'm wondering if 10k is fast enough. I usually cut thru thin aluminum, a bit of wood, plastic, and thats pretty much it. I really like the multipro series (up to 35k), but those are expensive. anyone know where to get one cheap? thx!
