Hypocrisy?????
Dear Say10, since you are relatively new to this forum, please bear in mind that you are posting in the New Members section. The idea is to help a new vaper with his/her problem, and it's recommended to read the original post carefully and come up with an answer that will best suit the OP. Most people who post in the NM forum are just starting to vape and their main goal is to find a PV that will help them transition from smoking to vaping. That usually means something simple that doesn't require setting up a workshop, buying a multimeter, torch, different gauge Kanthal wire, several sets of pliers and other tools, making cotton or hemp wicks--and the familiarity with the Ohm's law.
The OP said clearly that he's looking for a tank that will work "
out of the box.. without rigging." That, in my mind, makes the entire discussion about RBAs moot--at least until we hear from the OP again.
It's not a bad idea, you know. There are many people with all kinds of disabilities joining this forum every day. Some have poor vision, or poor motor skills, some are working moms and dads who have absolutely no time (or interest) in their busy lives to even contemplate rebuilding--they want plug and play devices that will help them quit. They don't care about intricacies of flavor, do not need a new hobby or view vaping as a competitive sport. They just want to quit smoking.
So yes, it's always a good idea to first ask the OP what exactly his/her needs are and how much they can/are willing to spend initially--just for starters--before offering suggestions.
Different things work for different people. There are many veterans on this forum who still use mini batteries with good cartomizers--because they prefer the small form and they don't mind constant recharging and refilling. I also know people who sold their mods (including ProVaris

) and use eGo-class batteries (vv or not) with simple tanks or carto tanks or dripping atties--and swear that nothing delivers a better taste than a Custom HH.357 Cisco Hybrid 510 Atomizer--not a Kayfun, not even a Vela Latina drip tank.
