Scuba tank,Hydro,Visual,tumble,Valve service,O-2 clean if Nitrox too much $$ ?

If you've already taken it someplace on your own to do the Hydro, spend $15 more dollars on a valve rebuild kit and have at it.  I have no idea what a full service hydro, vis, O2 cleaning etc costs, but having done a few, there is a lot of work involved.  Not to mention the stores have overhead as well. I've never heard of a shop requiring a vis after falling below 500psi.  I think I'd find a new shop to go to if that were the case.

If it really makes your Cheerios sink, buy a compresser and fill whatever you want, whenever you want.  I just got my compressor together, and when coupled with price the Haskel Booster and T's of helium and oxygen, I could pay to have a lot of tanks serviced and filled.

YMMV.
