I fill up at Tractor supply for $2.49 right now and U-haul is $5+ so only use that place if last resort. There are a lot of places that fill tanks. Look at where you get your CO2 filled (if you keg). Also as people already pointed out the "exchange" places are a complete rip off and should be sued for their practices.
I get about 3 10G batches on my tank. I think I can do better once I get my Jet burner dialed in. I had been keeping it at 100% and I could hear whistling but last brew I dialed it down then once I hit boil I turned it down some more to just keep a good boil. I got a spare tank off of craigslist for cheap. And I have had to switch tanks several times so it was definitely worth it.
