Wow - I just checked back to see if anyone responded to my thread. Really interesting reading and I'm glad to know that my case wasn't unique.

First, the northern Virgina dive shops meet regularly and have established "policies" that they've all agreed to support for their mutual benefit. Read the word "benefit" any way you choose. Even within this loosely established "consortium", some shops are easier to work with than others. If you would like Doc's list of winners and stinkers, based strictly on Doc's personal experience and not-so-humble opinion, PM me.
Second, not sure which tank monkey told you that tanks only need to be O2 cleaned each time they are hydro-tested, but that is contrary to general practice. Because oxidization inside tanks can be harmful in oxygen-rich environments, tanks used with partial pressure blending should be Visually Inspected annually - and whenever a valve is yanked off a tank, that tank and valve should be O2 cleaned. That means annual O2 cleaning, not only when the tank is hydro'ed.
Third, while its a huge PITA, you've ultimately gotta play the game or else set up your own blending station in your garage. One of the better approaches, IF you have a decent LDS in your area, is to take their Nitrox or Trimix blending course. Aside from building a working relationship with the staff of the LDS, you may be able to set up arrangements where you can clean your own tanks and valves using their equipment and supplies, as well as blend your own nitrox and trimix. Generally you'll see a considerable drop in per tank VIP/O2 clean price, and while the fills won't be that much cheaper, you'll get a blender's % reduction and have the hands on of doing your own fills. I've been able to do this with two local dive shops, and enjoy a very good working relationship with both of them. I recommend you consider this option.
One benefit is that you'll gain respect for the dangers of working with high-pressure O2, and the need to O2 clean religiously. An oxygen fire is a huge problem. If you're working with oxygen, you need to take it seriously.
I live in an apartment, and can't do the "T's of He/O2; compressor on my patio" thing. The next best thing is to have an LDS where I can walk in any day of the week and blend my own tanks, and annually pull a Saturday where I can rip down 4 sets of doubles and 6 stages, O2 clean'em, put'em back together, sticker'em, and fill'em.
Works for me. Diving air is not an option for me. This is next best to having my own blending station, and I don't need to store the tank tumbler, dryer, and stands all year in between VIPs.
Good luck,
Doc
