I have built 4 machines in the last 6 years. The first 2 I built my own electronics. The last 2 one wich was a plasma table I have sold. The last 2 I bought the Dragon Cut from CandCNC. Com. It's virtually plug and play and the price was around 900. For the price and the non worries its,well worth it. Phone support,built in Texas,and an unheard of 2 year support. They use all top shelf parts. It comes in a nice enclosure you just mount right on your machine. When I built my own I had almost that much in mine plus I had to figure it all out then mount it then wire it then trouble shoot it, no support or very little. Check them out. They mostly deal with plasma controllers but the have router electronics too.
