The old owner happened to be there today, when I went by to check on getting a 5lb bottle refilled, and he asked that his information be removed from this site, if at all possible. He also directed me to the following place, where I was able to get my tank refilled for $25. A little more than I wanted to pay, but they're the only game in town now and I live 10 minutes away.
