well for a newb i recomend you get an ego style device and a large smoktech dual coil carto, a protank, and a dripper atty, those 3 toppers are what you need to try to determain what you like best for hardware... everyone is differant !
then order sample packs of e juice from a few recomended vendors, halo sample pack, mountbakervapor sample pack, and diyflavorshack sample pack and see what you like for e juice. remember the same juice can taste differant in differant toppers ! you may like one juice in a carto and hate it in a clearo !
once you have been vaping for a wile and you have found a good all day vape and the gear is setup the way you want IE ego with protank or ego with a carto tank or ego and dripper atty you can buy a new advanced mod and experiment with rebuildables !!! remember to keep you ego and toppers for a backup !
so for a first mod i recomend an ego and a few differant toppers like a carto a dripper and a protank
for those who want something a lil better try a I Taste mvp and a i clear 30 setup and then get a protank and some carto tanks to see what you like
to underastand the differance between all the gear there is no substitute for experiance ! so go out and get one of everthing ! one good clearo one good cart one good dripper and one good top coil clearo and a good starter mod like an 1000mah ego or a Itaste mvp, once the gear is in your hands and you can feel and see it and how it works you will quickly get a better understanding of how it all works !
what i am trying to say is ... igues you need to just dive in and get some good recomended gear and try it out !
i would highly recomend the I taste MVP for a first mod ! its easy to use and easy to understand, you will figure it out in a single day of owning it, for toppers i highly recomend you get a protank 2 and a pack of coils, the i taste mvp comes with a top coil clearo the i clear 30 so you will have the opertunity to try out bolth top and bottom coil clearos to determain what you like. i would also recomend you pick up a simple smoktech or boge carto tank and give that a go too.
a setup like that will cost you
60$ for the i taste mvp and i clear 30
20 for the protank 2
10$ for the cato tank
20$ on e juice sample packs
so for around 110 to 120$ you will have a mod that will last you a long time and is capable of a lot of power and diversity as it has 3 differanrt thread patterns to use for toppers, and you will have a variety of toppers to use so you can get an idea of whats out there and what YOU like best !
if you want simple and cheap... well the 1000mah or greater ego passthrough and a protank would be the way to go this will cost around 50$ and get yourself some juice and few other toppers too over time
But I also found that everyone here were extremely helpful in answering and explaining all of my questions. It's overwhelming at first, but with time, asking questions and tinkering, it gets easier and in no time you will get it. Learn what equipment you have and as you advance you will begin to get it then before you know it.. curiosity kicks in as you start learning about the other devices out there, then before you know it.. you have this massive collection! 
I know.. happened to me.
