It is worth considering if you want to vape Mouth to Lung or Direct to Lung as this can greatly affect a suitable choice of set up. A lot of vendors will push you towards sub-ohm DTL devices & I've actually encountered some that look down on those of us at 1Ω & above. Not wishing to sound cynical, but they make a bigger profit on liquid than hardware & sub-ohm DTL devices tend to use a lot more juice than higher ohm MTL set ups. If you're coming off cigarettes, you may prefer a MTL device with higher nic content liquid. Jumping in the deep end with something too powerful or the wrong kind of hit could put you off. After vaping for nearly 8 years I finally got around to my first sub-ohm recently (largely because it came in the tank I wanted) I got on well with it, so I swapped the 1.5Ω that also came with it with my other half for the other 0.4Ω coil that came with hers. I've now got several set ups (after years of hovering around 1.8 - 2Ω) using 0.4Ω to 2.8Ω that I use depending on my mood & what type of vape I feel like.
If you can, try before you buy, it could save you lots of heartache (not to mention money) in the long run. Some get on fine with their first device, others hate it, then think that's all there is (after all vaping is vaping isn't it) & give up on it. Stick with it & don't be afraid to ask questions. Without ECF, I'm sure we'd both still be smoking, down to the wrong choices we could've & probably would've made at the start.
