Well I bought a zippo from a little antique shop for $8 and wanted to convert it to butane. I decided to buy a Vector Thunderbird Softflame Butane Zippo Insert instead of a torch insert since I have 3 torches already. It came in the mail today. Couldn't be easier to install. Pull out zippo guts, put insert it. Insert cost me about $14 shipped. Works great. Can't wait to use it this weekend.
