I got mine from My Vapor Store for $48.95 http://www.myvaporstore.com/Joye-eGo-ONE-Starter-Kit-2-5ml-2200mAh-Black-p/joye-eos22bk.htm There's also a 1100 mah battery out there so make sure you're comparing apples to apples.
Just received my Joyetech eGo ONE. So far this device is awesome. Ive only had it one day but so far its awesome. Tons of vapor and I haven't used the .5 ohm coil yet
Ah good point. If he has to rebuild the coil this just got difficult. Might be easier to just buy a tank with replaceable coils at this point in his vaping journey. Hey OP you got pics?
