Do you know anything about building coils, ohms law, resistance testers, etc? Mech Mods, Sub-Ohming, Dripping, are not as easy as just buying an RDA and VG
juice, it takes some knowledge to start that safely. If you have questions, i'd be glad to answer!
If you do, I'd suggest a regulated mod, like an iStick 30w, or a miniSigeliei 30w box mod. As far as dripper's go, RDA's are mainly about personal preference, do you want more cloud or more flavor? Doge, Mutation X, and Dark Horse are the thre top RDA's in my opinion. CLONES are sometimes just as well as authentics IMO if you get a 1:1 clone. Make sure you know about resistance and coils though, it will take you a long way. A GREAT build on a clone RDA can produce amazing results, trust me I know.
I have an authentic Pollux RDA (est cost, $120), and my $15 Dark Horse clone with the same build, on the same mod, produces the same results to me. Same cloud, same flavor. ITS ALL ABOUT YOUR BUILDS!!!
