As a route mechanic, I do a lot for my costumers. Stuff that my company would prefer me to charge. Keys in the pit, smoke test, Change door times, Lockout floors etc. So for them to have to pay for a upgrade every 30+ years, dose not seem too big of a deal. Also that price here in Canada is pretty much bang on. I pay more for cable TV/month, then most of our costumer pay for full maint.
