Found this suggestion on another forum and sure enough, the local U-Haul location had just the right fittings to refill my Performer's 5# tank for less that $5. Technically, the tank is dated January 2004, so it's due for recertification this year, although the attendant didn't even check the date. I suspect that unless something gives them reason to suspect the tank (rust, dents/dings, etc.), they probably don't bother.
