Both my wife and myself use Sophias and we also splurged and got "The Cage" tanks to go with them. I could be accused of shooting myself in the foot here because I would urge you to get a Real Sophia from Jeff at House of Mods, the clones are not in the same ball park at all and I know this to my own expense. Yes, I bought one, after the real thing it was awful, very flimsy, was a pain to set up properly compared to a real one and had a tendency to flood at any opportunity. Needless to say it was binned. I am the first to admit that a Sophia and a decent tank "can" appear expensive, well remember this old saying, buy cheap and buy twice, pay more and do it once! The heads are an absolute doddle to make and you will save yourself a considerable amount making your own. By all means buy some ready made ones with your Sophia and then watch Todd's review of the Sophia where he shows you how to build your own head, so you keep the ceramic cups from your pre made heads, buy some Res/NoRes wire from Stealthvape along with some 2mm Wick and you are off! With a bit of practice, you can be doing them for about 7p a shot. Good value or what?
