David if you are in So CA, and I think you are......just start calling the local propane retailers in your area. Google or the yellow pages if you still get them.

Ask them if they have a minimum, what the rate is per gallon, IF TAX is included.....you should be able to get a FULL fill for around $18 bucks. I have found the UNOCAL 76 stations have the best rates (at least in the OC). I have one next to my gal pal and one around the corner.

I only use Blue Rhino when my tank nears expiration and I cherry pick the dates on the exchange. Cheaper than buying a new empty tank. I have four tanks, two at the GF and two at my house....I hate running out in the middle of a tri tip.

BTW, the BTU rating on NG and propane is diff and exchanging tuned burners is a good idea for proper burn and temp regulation.
