Where to find 5lb Co2 in Miami area?

[SFB]

Hey everyone, sorry this is my first post and not sure if this is the best place for it, but I am at a loss. I have built my own kegerator but I can not for the life of me find a place in S. FL that has 5lb Co2 tanks. I have called welding supply, beverage supply, and fire fighting supply companies and no luck. Everyone I have called has much larger tanks and has no clue where to get a 5lber. Anyone know of a place down here to pick one up? Or am I going to have to buy a tank online and get it filled?

Dive shops. I got mine from a diving guy about 6 years ago. Dont know what a dive shop was doing with a 5 lb CO2 tank, but hey...it worked for my college kegerator.
