Ok, who is using one? Is it any good? I see name brands like Skill and
Milwaukee making these. Would it be good for cutting something like
1/4 -1/2 inch plate?

I already have other tools, but
Torch - messy cut.
Bandsaw - limited cut size.
Abrasive circular saw - messy environment relatively slow.
Plama - expensive and don't have one. Very limited thickness relative to
price.
