Similar to above I would like to know the best/cheapest place to buy the upgrade kit (V1 to V2). Fasttech seem to sell the full V2 kit but the shipping date seems to get longer and longer and the price is not that great. I am really liking the V1 but struggling with vertical coils and dry hits. I currently have a dual coil inclined (ID 3mm .40 Kanthal six wraps @ .49 ohms) which is wicking OK but not amazing. My last build was a very shoddy horizontal affair that looked like shit but tasted/wicked great. I seem to find this a lot with my coil builds in general (the shoddy looking efforts work far better than the photogenic ones). I keep trying to tweak the wicking but can't seem to get a vertical setup to work.
