I have a 10lb steel CO2 tank currently and was trying to get another tank just for backup/adding to my setup...I came across an opportunity to purchase a 20lb ALUMINUM CO2 tank for $75 and the hydro is good until Sept 2010.
Should I go for it? It seems like a pretty good deal to me since I got a 10lb steel one from ebay for like $70 or $80, can't remember exactly.
One thing before you purchase, make sure the tank doesn't have Pepsi, Coke, or some other owner info. stamped into the bottle.
I bought a blue 20# CO2 tank and I didn't know about the owner stamp. Now I'm having a tough time getting it filled. The welding supply shops won't fill it as it has the Pepsi stamp. Do a search and you'll find other threads. Some areas are of with filling them, others won't touch em. Good Luck...
I went and picked it up...the guy used it for homebrew himself but did not need 2 20lb tanks. It was produced in 2005 by the Catalina Cylinders Carbon Dioxide (CO2) Cylinders and I did not see any pepsi or coke owner info on it. Unfortunately it was empty but hey, it was in great condition.
