Has anyone recertified a refillable propane tank recently

What is the cost?
Is it a hassle?

I have Manchester 40 pounder in great condition that's closing in on 12 years 09\01.
Just got it refilled and the guy at the welding\gas place said it's getting close.

They cost too much to toss out so it needs a new date.

Appreciate any and all help.
TIA
