No, it isn't silly, because the service time is similar. Is your time worth less when you're overhauling a small piece of gear like a regulator than it is when you're doing a small job like an oil change on a big piece of gear like a car?mattboy:Well, this analogy is a little silly, because the service on a new car is a tiny fraction of the cost of the car, where the service on a reg can easily exceed the cost of the reg over the long haul.
Now, the decision to service or replace may have something to do with the cost of the whole unit, but it does not bear on whether a technician or mechanic should be paid a fair wage for his/her work. Calling a fair wage a "ripoff" based on the cost of the gear being serviced is BS.
You're always free to buy the special tools and parts and do it yourself - as frequently or as infrequently as you desire. That's what I do... but if I decide to have a shop do the work I expect the worker to get paid.
