Out of curiosity, and since the prices aren't listed on their website, I stuck the name in Google.
PlasmaCAM 4x4 CNC Plasma Cutting System | eBay
Is it really $700k?
Maybe to buy the company!

Last I had heard the complete turn key system was in the neighborhood of $15,000 top of the line. I think they start around $7,000 with out a computer. You will also need a very good ventilation/exhaust system as plasma generates a lot of smoke and fumes.
Their statement about not accessing their email, gives you an idea about the the response, to problems the owners of the equipment might have. It also explains why the people complain about no or slow response to email inquires.
The other thing that would give me pause is their lack of a complete description of what you get for the money. Other than the Red color disclaimer in the statement.
I do know that the only ones that seem to be making money with them already have a metal working shop and have a customer base that can use the service.
I also know that a person that with a good air compressor,plasma cutter and some templates made from Masonite or even cardboard with a little practice can cut anything out of steel. That they can cut the shape into a template. Taking into consideration the minimum plasma cut kerf size. There are limits to the radius and thickness of the material.
Plus it is a lot cheaper to start out with, don't know how many cut outs silhouettes of kitties, puppies, dogs or old fat ladies bending over you can sell to cover the cost and operating expenses!
