I have some air shears (like air powered tinsnips - pistol grip) good to 18 gauge that are an absolute blessing for cutting (clean) sheetmetal. Last forever with care (unless you try and cut rusty sheetmetal). You can do wide radiuses fine. They also produce a nice consistent curl of sheetmetal about 1/4" wide that comes in handy frequently for little gaps and such.
Also have some air nibblers that as klhansen says above, work fantastic for tight/odd/sharp angles - but I second that "watch for the little crescents". They get everywhere and somehow find their way into the house. I worry about the shop cats too, I use those over a bag/container where possible and keep a magnet handy. Even at that, some escape.
