I refuse to swap. I don't want some rusty steel tank for my aluminum darlings.

I don't think I've ever been to a place that fills co2. HVAC Supply houses only swap. Some of the steel tanks have been in service over a hundred years, you can see all the hydro stamps on the neck and foot. I could see how people would like "new and shinny" but for me, it's just another tank. Next time I go in to Airgas, I may trade up sizes or down, or for another gas like beer gas or C25. I understand that many would not want a nasty old tank in their clean house, but my house is not that clean. A nasty old tank fits my Ambiance, makes the statment "this guy likes beer and guns and girls that are a little crazy". Do not mix any of those things.

At least you won't get no Alzheimer's from steel...I got my tetanus shot though....

In general I'd agree, but if beer or another liquid backs up into a steel tank (which can certainly happen under the right conditions) it'll rust and lead to some funky off flavors. Actual "food grade" CO2 cylinders are supposedly glass-lined to prevent this. For me, I'll stick to my new shiny aluminum tank, who knows what's happened inside the old rusty steel one.

The "aluminum causes Alzheimer's" myth has been busted long ago.

Or what has gone on inside your "new" tank for that matter. Plenty of people have bought brand new Regulators only to find that they were not cleaned. The weld shop I use says most aluminum tanks come out of China or South America, so who knows really inside any tank. But these guys come over to drink at my place so they know where it's going (they also breakdown the tanks and valves for certification)

I had no idea a co2 tank could be glass-lined. Can you give me more information on this? Link?

Unfortunately no. Everything I've read about it has been on forums, I have nothing solid! The whole "food grade vs. non food grade" CO2 debate seems to be completely anecdotal. I can't find any hard evidence one way or another, and I can't find anyone selling glass-lined tanks. The only place is mentioned is when people talk about "food grade" CO2.

That's true. The number of new regulators that don't work due to crap in the diaphragm is pretty astounding, judging by all the "help my new regulator doesn't regulate" posts.
