Where are you in Canada? I am in SouthWestern Ontario. I have parts from a huge CNC router that would be perfect IMO to adapt for plasma. You could get it for a good price. If you're interested, send me a PM and we'll talk and I can send you some pics. It will do 5x10.
It's so big, I don't really see how we could ship it if you are far away, but if you're close and want to make a deal, or at least discuss it, let me know.
