For value shopping there are lots of different places to look. First step needs to be thinking about the tons of places that use CO2. Brew suppliers for home brewing, Bar/restaurant supply for beer or soda, Auction disposal places who clear out closed businesses, Used from local users who are giving up kegging or raising plants like weed or planted tank folks. Lots of options.
Really the sources and where to find value is more a matter of how well you can shop as well as what you perceive to be the "best buy" for you personally. At times, I have weeks to shop so will look for cheaper prices while at other times, I just want to get it running and may go to the local store for quick and easy.
My last tank I bought in the Tampa area came from a closed Burger King out on Holmes Beach.
