and you keep twisting my words. I said germany is one of the only, pointed out two other countries i wasn't sure of, and you are taking my point about service far too literally. You can obviously service any reg you want, but if you can't buy parts for them, that effectively renders them non user-serviceable, and since you can't buy parts in this country, or any other country except for Denmark, the Netherlands, and Germany, my point still stands, especially since they aren't allowed to export to this country without losing their dealership status, which has happened before.
Yours however, does not because the cost of parts kits is offset significantly by the difference in purchase price of the regulators, so either way, you're paying for it one way or the other, the difference is if we followed your plan, it would take 10 services per stage to pay for the up front cost difference which is 10-20 years depending on how frequently you service your regs.
