I ran SIP and DeVleig jig borers and grinders for Boeing. SIP makes the best machines I have ever run. Sorry to bust your bubble pops. Lots of younger people run precise machines. They are fine machines. Moore also makes an excellent machine you don't see very often any more. Fellows gear shapers are also very nice machines.
