I would get #30 recertified. #20 cylinders are easier to exchange at HD, Lowes etc and the clerks often let you paw through the cabinet to find the latest date. That is (out of date) a valid reason to exchange per the exchange companies.
Well I took my empty tank to the local full service Propane supplier. The valve assembly failed on both tanks (leaked) cost of new valve was only $20 less than new 30# tanks, so replaced both.
Took DD's 20# tank to same location as it was past date, and exchanged it for a new tank with likely 15# of propane, but the tank was brand new.
