propane fire pits

And propane torches purchased in retail stores (K-Mart, Home Depot, etc)?
Information on these shops have bought homes propane. How long does it burn? Cost for a duration of approximately 5 hours. Any suggestions that work best? Last longer? I look at those who seem to have a stone or more burn more area than they would in a small courtyard.
My favorite is the campfire Castlerock The Home Depot. If you go to homedepot.com and type Castlerock fire "or" 3-6242-57-0SL "in the search appear. They can burn propane, but fairly quickly, especially if they're in the highest setting. Expect to burn 1 gallon of propane averaged over a period of 5 hours. Therefore, to $ 3.50 a gallon, you look a little less $ 1 per hour to operate. The hardest thing is to refill the propane tank or exchange 5 gallons every week if you use every day, 5 hours per day.
