I started out with the V2 e cigs also. It didn't take long to move up. My second kit was the Kanger Evods. I really liked the Evod tanks but didn't like the short life of the battery. My favorite now is the iTaste MVP 2.0. It is a box mod and lasts me 2+ days. I would recommend the MVP 2.0 and for tanks the Kanger Evod and either the mini Protank 2 or the Protank 2. The Protanks are glass and with withstand any liquid you want to use. You can get the MVP and a couple of tanks for much less than $100. Good luck and vape on!
