^ I worked at a shop that was too cheap to buy a metal chop saw, and put a metal blade in it. I could hardly cut 1" .120 wall tube with it. It just glazed the blade over. If you're set on that, I'd want to try it out on some 2x3 first.
Personally I don't think tools are the right place to be cheap, but I've done it myself. I say this though, because every time I have been cheap when it came to a tool, it bit me in the ass.
