This is the original...Mine is probably 10 years old or so?? Still using the original ignitor and has been on more trips than I can even remember?? The new jetboil stoves look silly in my opinion. I have no idea why someone would pay more for the same thing?? even the TI version is not light enough to justify the cost. This is the only jetboil I use. If you really want light weight, nothing is lighter than the pop can hobo alcohol stoves. Takes up about the same amount of space for everything in my pack but weighs less than half of my jetboil set up..
