How much use is a plasma cutter?

[The V8 Files]

Ok I'm still selling bits of my donor and using the money to buy tooling etc, one of the things I was looking at was a plasma cutter, initially for cutting the donor up and then using for the build.

I'm just wondering though how much people have actually used a plasma cutter during the build and if its a worthwhile investment or if I'm better putting the money into other things.
