I have a Dremel one i got in a 3 tool bundle. It doesn't have quick change on my model, which is pretty annoying. I would at least narrow your choices down to ones that do! Mine is also corded, and the cord is like 3-4 feet, so that is also annoying. But its got power to handle most everything i needed it too. Accessories are expensive, especially sand paper. I always hit up Menards when they have their cheapest brand on sale.
