I agree with some of the posters here but not all.
I did all that massive airflow, chuff caps, ridiculous boxes and now I've upgraded to this style nowadays
You see the dodgy looking box next door, no good IMO. It's friend is A great little piece which vapes like you do now, nice and mtl. I only go about 10/13 watts but I build my own and DIY and stuff so... Like one of the other guys who posted, this is a little tricky for a beginner so I would recommend getting a vamo, or provari (you Americans get great deals) for the main body
And get a nautilus mini as the atomiser.
Your rig could look something like this
Obviously colours and that dodgy looking lip and drip tips can be changed and because of the ergonomics it feels as though your 'smoking' a classy, healthy, cigar sort of thing.
Admittedly the size is a little hard to get used to at first but it happens and you'll be really comfy.
You might grow to love the huge clouds and 100 watts like I did but now I don't. I feel much more comfortable with something like this now.
Most important thing for a rig like this is external good quality batteries and charger from a reputable vendor.
Get a couple batteries which fit your device and vaping like that you can definitely just charge one while you vape the other and go all day on an 18650 battery. This particular mod takes smaller batteries I think, but just shop around.
YMMV
