I am a recent and proud converter from Weber to the Big Green Egg. I had been the utilizing the Big Green Egg brand electric starter from the very beginning. I just transitioned to the Bernzomatic TS4000, which I purchased from Lowes a couple of hours ago. There is certainly a night and day difference. Can anyone using the Bernzomatic TS4000 tell me how many applications i will achieve before a required MAP refueling is in order?
