Are you talking about the panel king? It's basically the same thing Paul and I mentioned. I'd go the vertical route like we mentioned above. Vertical saws are far easier to load, and less space taken up. We have some large vertical panel saws at work,

Although it would take more space than the ones shown above, you could add the ability to move the saw in the x direction.
Not sure what your budget is, but the cost to add CNC to a machine like this probably could be done for maybe 500$ or less, depending on how fast you want to go.
