Indeed I do seee your point, it isnt about the cost of a annual, just because it is a dive shop doesnt mean it will be done right, I would be willing to spend money on tooling up! and training ect 5k isnt that much, really I easily have over 10k in gear now, I just have a hard time trusting someone I do not know. I trust myself, I never send my vehicles to the shop nor Do I have a contractor work on my house, and why poor quaility control when you out source. If you cant or dont have the ability or even doubt your ability I understand to the dive shop you go. But it isnt voo doo magic, and dive shops do make many feel that way.
