Used to like Ronson. Have gotten away from them, never know how much gas is left and they've left me stranded a couple of times. For a cheaper price I've ordered half a dozen 1300C single flames from dealextreme.com on a couple occasions. Usually around $3 with no tax nor shipping charges. They hold a ton of fluid and you can see it, plus the flame is a true flame that blasts. BTW, I've been running Ronson fluid in these for years (dozen cans or more) and have never had ANY issues (sorry, Greg).
