Cutting sheetmetal, whats the easiest way? Options

[Verruckt]

I don't really want to invest in a sawzall right now. I have an angle grinder with a cutoff wheel, but it's going VERY slow and making a hell of a racket and mess...

What about a pneumatic nibbler? Or I have also seen what looks like an air die grinder with a small cutoff wheel and a guard on it, are those worth a crap? Trying to get out my floopans, and will have some other misc. sheetmetal parts later on to get off.

Anyone have some experience before I waste some more money trying everything under the sun?

When cutting metal on the car, besides an electric grinder with cutoff disk your options are sawzall, jigsaw with metal cutting blade, plasma cutter, nibbler, or air cutoff tool. The air cutoff tool requires a lot of CFM for continous operation so you better have a big compressor (like 15 scfm or more). I've never used an air powered nibbler but I'm sure they have their place for certain jobs. I do have an air shear and it's great for new flat sheet steel. Some people hate them but there a trick to using them to keep them from binding, then they work slick.
