Spydre thanks but I don't wanna buy a whole new tank to use if I don't have to. I have purchased so many different ones Kanger EVOD, T3,Protank,DID Clone,iSmoka BCC, 510 Locking UDCT, C3. I think I might get the Smoktek Terminator tank since it looks pretry good for on the go. And use my Steamboy & Locking 510 for at home. And Joe thanks I found some cartos that are like 2.00. I appreciate the help guys.
