Everything sounds reasonable. I don't spend much time in Dive shops. I generally fill my tanks at the fire house and do my own thing.
The valve is a non-issue as I am replacing them with new Thermo Pro Din / Yoke type. I didn't want to confuse the question by adding this but it seems I did since the valve is an issue.
I was quoted
20 for the VIP+
50 for the hydro
150.00 for the "oxygen cleaning"
65 for the new valves.
Now, I was certainly born at night but it was not LAST NIGHT!!! I confirmed the cost with them three times in the conversation. When I said that is more than the cost of new tank the responce was, "almost, that is the way most people go." Well the way this person is going is to another Dive shop!!!!!!
I'm not a shopper, most of the time. I didn't even blink at the 175.00 I paid for the certification course. In fact I never even asked the price. I'm sure glad I didn't just drop off the four cylinders and tell them to call me when they were done.
