There are almost as many "perfect setups" as there are vapers. Because "perfect" is different for every vaper.
I would recommend a high quality mod. There are many, like the provari, evic, vamo, sigeli zmax, lavatube v2, etc. for this I would get what you can afford, as a good one will fit anything, and work well with everything.
Then when choosing atomizers, tanks, cartomizers, clearomizers, whatever, you will probably just try different things till you find what works for you. A Vivi nova, vapeonly bcc, evod, or Kanger t3 are all pretty good places to start as they all work great and are easy to use.
