I transport S size (154CF) tanks to fill about once a week right now in my car and that is my limit comfortably. They stand about 4 feet high and weigh a little over 100 pounds each but do keep in mind that you never have to really carry that much weight if you learn how to roll them upright. I stick with the smaller tanks because it is comforting to know that I can handle the full weight if needed. Each fill costs me $18 and a tank lasts me about 5-7 days. My Propane BBQ tanks seem to last almost indefinitely. I am running a GTT lynx and I like to make solid sculpture and marbles out of Boro glass. For these items a concentrator would be somewhat limiting with this torch. Is there tanked Oxy available to you locally?
