Generally speaking though the term "high definition" most usually is associated with the plasma machine/torch combination, not the CNC table.
I only know of 1 person that is using a Kaliburn plasma machine. It seems to work ok, but for my 2 cents I'd rather have a Hypertherm Powermax 1650 as the machine they have.
It all really depends on what you are planning to do with & how much the machine will run weekly. Just about any table with good tight but smooth movement will carry a single plasma or ox/fuel torch.
Software is also a key issue. It makes the learning curve much easier if you can use the software without having to attend a semester of school to learn it.
