I'm totally overwhelmed with info on all this and don't know where to start. I've been reading dozens of threads on rba/rda's and rebuilding atomizers for the Kanger I have wanting to save money on buying coils and it seems everybody has mods or at least vv/vw's with the rda/rba's and we have just regular ego's and no money for new batteries. We are on an extremely tight budget so am I better off rebuilding coils or should I get a rebuildable? I need something new for my DH either way, he's been using little 510 t4 clearos and nobody has them in stock anymore and he's finally using an ego batt. I want to try dripping so I've been looking at rda's for me but want to stay close to ego diameter and for my DH I would need a tank that doesn't leak and is also ego sized and all the recommendations are big and heavy. The rda for me is easier but an rba that is cheap, small and doesn't leak seems impossible-- and do we really need a mod? Any and all advice is welcome, thank you!!
