For now, I have the M Tank on mine, and I just avoid the tank cracking juice. Everything else I have is glass, so it is not a big issue. I did look at the stuff from Kidney Puncher that someone linked above, but I have an issue paying more for that than I paid for the Kayfun in the first place. My guess would be, as with everything else, those prices will come down in time to something we can actually afford.
