I have 3 propane cylinders to give away. One 30# and two 20#. The 30# leaks where valve screws into tank. One 20# has a bulge in the side. I'm not sure of the condition of the other 20#, but I do know it's older. I would not recommend filling any with propane as they are. If you have a use for them, they are all yours. You must take all 3.
