Great news....thanks to both for replying.
There's no place around my area that just exchanges them. Its either you own the tank, or they own it. Otherwise i'd just exchange and not worry about the testing. But for this latest tank i was asking about, i can't complain...its pretty well full, came with a regulator, faucet, and sanky connector all for $30 CDN
