Re: Looking at plasma cutters...
I'm not sure what you mean by "good ones". Those are pretty much the cheapest cutters available. They probably will work fine for you, assuming you are planning to use it in a home-shop sense, every once in awhile, for a varying amount of time, and not most of the time every day.
Make sure you can get parts for the torch (there's a couple of parts that are effectively consumable that you have to replace regularly).
You also need a source of clean, dry air for it (of sufficient pressure and CFM).
