Congrats on the great deal!
We sell the pci card for 650 and fully support your machine 7 days a week. The team at Armor CNC were electrical and mechanical engineers at Techno before the name was sold in 2013.
Let me know if you're interested in keeping the machine stock. We can make a deal on a pci card + computer combo to save you some $.
We also have a kit to convert the machine to mach4 but it's more expensive because we keep it servo, we don't switch it to steppers.
Regards
Eric
