When you tell me what you do in YOUR business I have no reason to doubt it, and good for you, 36 years and a great business, yet when I explain what we do (38 years and a great business) then it becomes a problem.
I have had a cimex, 10-12 OP's rotaries, Crb's, Tm, porties and I have a years running each, yet I prefer something "different" from you for "different" reasons.
