OK, so call me old-fashioned. I would recommend a Kanger Evod or Kanger Evod 2 setup to see if vaping will work for you. The original Kanger Evod uses single coils, which are very reasonably priced for genuine Kanger coils. They can also be cleaned, re-wicked, and/or rebuilt, depending on your preference and desire to prolong coil life. I do not rebuild or rewick, but I manage to get an extra 2-3 uses from each coil by cleaning them. The Kanger Evod 2 uses dual coils, which are also reasonably priced for genuine Kanger coils. Evod and Evod 2 starter kits are very reasonably priced, and usually come with 2 batteries, 2 clearomizers with coils, and usb charger. For my daughter and myself, they provided a very satisfactory vape experience at a price we could afford.
I would also add a glass clearomizer such as a Protank or Evod Glass. Some eliquids are known as "tank crackers" and can damage the plastic clearomizers that come with the Evod starter kits. These are also very reasonably priced, and use either Kanger single or dual coils, depending on which model you get. My personal preference is for the Evod Glass with a Kanger single coil in the 1.8-2.2 ohm range. My daughter prefers the Evod Glass with a Kanger dual coil in the 1.5-1.8 ohm range.
We use eliquids from various vendors, and these clearomizers can handle most eliquids that we have tried in the 50/50 pg/vg to 70 vg/30pg range.
It is up to you, and your budget. Do your research, and look at what you think might suit you. My daughter prefers the "stick" form factor, so for Christmas I got her the Innokin VV v3 battery. I wanted something with a longer battery life for when my beloved NY Rangers get into the National Hockey League Stanley Cup Playoffs, so my daughter and her boyfriend got me an Innokin CoolFire IV for Christmas. My daughter's boyfriend wanted to "blow clouds", so I got him a Kanger Subox Mini starter kit for Christmas. All of us enjoyed our Evods, which are now our backups, and we are all enjoying our new hardware.
