I want to start to try dripping some juice but before I jump all in I would like to try an inexpensive 510 connection bridgless atty to run on my eGo C Twist... any recommendations? I bought a couple from a store I won't name and both came DOA... ( I am working to resolve this ). You guys have helped out a lot in the past and have never steered me wrong so I am looking for some recommendations that will get me started and not break the bank.
