I kind of lost track, are you still looking to get your Dad a "cig-a-like" or are you going with a bigger battery?
I think ill end up getting one of each so either i can take one or he can have both with variety. But i have heard many good things about the katana, so ill prob just order him both. Leaning to introducing him to the Smoktech cartomizer, ego battery and charger as a starting point. Then when he gets used to it ill show him what i was using (til the katana comes) whcih will be the Vivi nova tank system and the ego c battery. ( i think i got that correct on how i want it to work out)
Vision Vivi Nova Tank System (with drip tip) - $12
SmokTech 510 Single Coil Cartomizer - $6
JoyeTech eGo Upgrade 1000 mAh Battery - $22
Then
Charger- - $7
extra battery(ego c) $12
@ocelot, where are you ordering from? and do they have everything in stock?
Im doing this with my mom, she tried a cig2o and threw it in the drawer.
