Odd Shape CO2

Has anyone seen these size CO2 tanks?

It is a wicked good price if it works.

I think the biggest issue would be getting it filled. You would need to find a location that will fill tanks as opposed to an exchange program. I doubt that any of the “normal” exchange sites carry this style tank.

I have one of those that I converted from an O2 to CO2, and yep, it’s expensive to fill since I can’t exchange it like a regular tank (costs as much as my 20#).

All-Safe has those I don’t like them as I think they can tip over easily, but they sure don’t take up much space.

Thanks for the input guys, I didn’t even take filling into account.
