Should I get a plasma cutter/will I use it

[Burt Shaver]

If this is something that ends up being used twice a year, is a warranty really that important? If it fails on the third use and the warranty is already expired, it didn't really do much for you. At least with the cheap ones, if it fails, it's just a throwaway thing anyway. You just buy another one

Good point,

They're not as cheap, but if you don't have an oxygen/acetelene rig in your shop for basic freeing or heating of parts along with the cutting abilities, I'd start there.

Plasma will deal with rusty thin metal far better than Oxy acetylene and the run cost is way cheaper than running a acetylene torch.
