Cheers Jeff, I think I will get the one in the aluminium box, not very good at electrical stuff. One question, it mentions plug ins and alteration to Mach programing, I installed Mach some 3 years ago and haven't touched it since. I take it would work on an old Dell Inspirion 8500 in excellent condition. I have loaded Mach onto it and put my xml file in and it all works on the computer beautifully the ports and pins match my old machine. I have read your set up literature but still a little confused about plug ins
