Actually, most handy tool for metal is a 5" angle grinder. You can put cut wheels on it and cut any size or shape, grind wheels for heavy material removal, flap discs for light material removal or even polishing, and wire wheels for removing scale (rust).
If I had the money I would get a Port-a-band over a chop saw; cleaner cut, less mess(no pile of grit), less heat put into the material being cut. (Of course a cold saw beats all, but unless you are indepentantly wealthy, or a professional fabricator don't even bother).
