a jigsaw would work fine too, it depends on how straight you want your cuts I guess. maybe I just suck with a jigsaw! lol :footinmou
I have a bi-metal blade for my jig saw, 24 tpi if I remember right, anyway, it works just fine, might help to have a variable speed saw too tho. I don't like to have it wide screaming open, tends to kill blades a lot faster.
I like the die grinders because they are just a little bigger than the dremel and the blades made for stainless make a pretty quick/easy job.
