    The most expensive one you can afford:
    You get two types:
    - HF Start (around $200 mark) - can be made to work, but if you are a beginner at electronics, these have a LOT of EMI to deal with (so expect to spend some time dealing with that by adding ferrites, earthing, and shielding)
    - Blowback Start (Hypertherm's CNC range for example) - usually costs more, but initiates the arc with a piston getting blown back by the air pressure, no nasty High Frequency Prearc like the HF ones. Doesnt make as much EMI, and therefore a lot friendlier around electronics.
    The better vendors also have a CNC control port right on the machine.

    Refer to OpenBuilds BlackBox 4X Documentation for more details - pretty simple in its most basic form

    Of course you can complicate it more if you need to (different controller that supports Torch Height Control, add a Torch Height Controller (Definately needs the expensive plasma inverter that has a THC port) etc
