If you're cutting aluminum, and want straight cuts, get a metal cutting skilsaw blade. FAST, and straight. Will work well for steel, also. I usually cut steel up to 1/16" with them, and aluminum up to 1/4, 5/16 is no problem. I use the Makita 18v cordless metal cutting saw for straight cuts in sheet metal and flat bar up to about 1/2x8. It leaves little to no burr, collects most the chips, and is fast as cutting plywood up to 1/4" material. Battery life not a constraint. A skilsaw with a non-ferrous cutting blade.

The jigsaw is plenty fast enough for smaller jobs, but the grinder is more useful. But it doesn't got anywhere near fast enough to plasma cut sheet metal. That's besides the fact that it takes to long to setup for such light cuts. As for the saws suggested. I've used them in the past as well.
