arrow 750 cnc 1994 model.
anybody have any suggestions what would be a good retrofit package for my mill. and money is very tight so i would need the cheapest model that would work.

My Retrofit of choice is Fagor.
IMO it is not expensive for what you get, but the trend on this forum when people say "cheap" is that this setup will be too costly.

Hey Chaz, we retrofitted our 1995 Arrow 750 with a MachineMate controller from MAG (formally Cin. Milicron). Compared to the old CT, this system rocks!
We offline program so I cannot advise on the controllers programming but without the retro we would have scrapped a great machine. I can give you a contact if your interested. Not sure what the cost would be but it would be worth every penny. The setup on the control very easy to learn and the screen layout is decent. Windows computer controlled with touch screen. Any questions, PM me or post.

Yes, for me the better choice is Fagor. In the 80 percent of the retrofiting you can use the same drives and spindle driver.
