Okay so right now I am vaping on an mvp 2.0 with a mini protank 3. I like it for how cheap it is but I'm looking for something different. I am hearing a lot about the nautilus mini as well as rda/rba. It sounds like people who are using these could never go back to regular tanks. I only buy the mini protank 3 because I can rebuild it. I hate spending money on coils. I heard you can build the nautilus mini as well. But if that's the case wouldn't an rba be better? I don't think I would like a dripper cause that seems like a hassle.I guess my question is what would the best beginner rba/rda be. Also would I need a new battery. I haven't found a guide on this yet. When first looking and seeing all these $200+ devices it can get overwhelming. I heard some about the kayfun lite. That seemed relatively cheap. Anyways any help would be appreciated on what to do next.
