I had a '86 Leadwell MCV-0 with a Fanuc OM control, 16 tool carousel. We sold everything off in '95, and the machine was still running pretty good, the iron was fine, still a very accurate machine.... just had some issues with the tool changer... needed to replace some air cylinders and cushions, guess they wore to the point of being unreliable timing wise and we'd get faults during tool changes.
The original steel way covers on the X axis were crap too.... they fell apart within a month or two. I drew up and had Gortite make a couple sets of rubber accordion way covers and we never wore out the first set.
I actually like that little machine better than the Fadal 4020 we had. I have no idea what the current situation of getting parts would be, but everything was pretty much off the shelf components.... not sure what you'd have to worry about.
