I don't know if anyone has tried this out or not but I use cartomizers on my prodigy.. I have regular 901 atomizers but the cartomizers work as well and cost a whole lot less. Cartomizers are marketed as being disposable but I have been reusing mine for a long time. The atomizers in them last as long if not longer than regular atomizers and you can get 5 of them for 6-8 bucks. Some of them don't have enough air flow but that is solved by putting a tiny hole in the cartomizer towrds the bottom, (where the 901 atomizer has one). They are so much cheaper that I have a bunch of them and don't have to worry when one burns out. Just a thought..try it out. Mist stix has cheap cartomizers.
