I couldn't agree more! I am in the process of switching my stage cylinders to MK11's and G250's.This is among the reasons why I am slowly dumping everything not-Scubapro. And I cannot apologise for it. I am trying to standardize on regulators that all use the same service kits and can share parts. The yoke assembly and Universal DIN kit for Scubapro fits most of their products going backwards. And a Mark 2 Evo is possibly the most reliable regulator ever made and the Mark 11/17/19/25 are superb in their own. And a 109/G250/G260 all use the same second stage basic service parts.
My wife does not know it yet as she has a new Core Supreme and I just serviced her first generation Legend but she has a G250 and Mark 2 Evo in her future to match mine.
