Since I have several kinds of saws, I'll throw in my two cents on this one.
If you're cutting long straight cuts, stick with a band or circular table saw as a scroll will limit length
If you're cutting small parts with sharp curves, a scroll saw is better but it can be done with a narrow bladed band saw
If you're cutting across long stock, go with a scroll or circular table saw
If you're cutting inside curves or circles, go with either a scroll saw, jig saw or drill press equipped with a hole saw
If you're looking for a saw that will do it all, they are presently made of "unobtainium"
