Review and advice
Some advice: I use Praxair for my cylinder exchanges (welding gases and beer). They are all over the U.S. within a few miles, no matter where you live. Make sure you exchange your 5 lb Aluminum for a 5 lb Aluminum. Don't let yourself get downgraded to a steel cylinder by carelessness.
Home Depot sometimes has cylinder exchange lockers, but probably not aluminum CO2 tanks, you'd have to check. Don't be afraid of the exchange! You'll get a freshly inspected aluminum cylinder, which is a good thing if you're toting around kegs to parties, etc.
