Spectre once bubbled...
In hindsight however, I would have purchased an AL40. A friend of mine is thinking about picking up a pony, and I'm thinking of unloading this on him [if I don't think of a use for it... argon? probably to big. O2 kit? possibly....] and picking up a 40 instead.
You can probably sell it on ebay, pick up a 40, and walk away with some cash to boot.
