I have noticed there are two types of cutters for sheet metal. One a
nibbler, one a shear.

The one nibbler I see apparently cuts out small pieces, almost circles, and
imagine that would be for very fine work. The other "nibbler" has two
blades that are about 3/4" long that go up and down, pinching and shearing
the metal.

The third is a shear, much like a pair of electrified scissors.

A brief description of each and its use would be appreciated. When it comes
down to it, I will probably need all three for various stuff.

And lastly, I see some run on air. If one has a good compressor, is there
any important differences between the electric and air models?

This is going to run a few bucks, so wanted to ask first.

And is buying refurbished worth the savings or not? Problems later vs: new?

There is actually another kind that is a rotary shear. I got two
variable speed electrical ones at an auction sale at an aircraft repair
shop. These allow you to see where you are cutting and allow all kinds
of curves, etc. Actually cut faster than I like! Just need to practice!
