Hypertherm is definitely the class of the field. From my fairly extensive research the Everlast is a very powerful and dependable machine that is easy to fine tune to a table and get precise cuts with clean air. With clean air they have about 70% consumable life in comparison to a Hypertherm. Considering the cost difference and all of the other things that had to fall in place for my project is why I went with the Everlast. (I had to add on to shop, purchase new compressor, a CNC table, etc.)
That said, if I was ONLY buying the cutter i'd likely buy a smaller Hypertherm unit.
Keep in mind that the CFM ratings on your compressor and air quality (dry air) have more to do with the life of consumables and quality of cut than the machine itself. If you have a baby compressor spitting air through the machine you will never have a nice end product.
