Have you tried calling around to propane companies in your area? Don't be discouraged if one or two say no. My wife spent an entire day calling around and she found a guy a few hours away that sold us 4 tanks (2 250's and 2 120's) and delivered them to our house! He was going to scrap them and we offered him more than the scrap yard which wasn't much... Now he's a contact of ours and is actually holding a couple more tanks for us right now. We have found a couple other places to, we'll be picking up another 120 tank soon to build a maple syrup evaporator. We haven't had much luck outside of dealing with propane companies. Your luck may vary but that's the route I would go if you haven't already tried.
