Hi, Carbon. Welcome to ECF!
And congratulations with choosing to make the switch from tobacco cigarettes.
There are going to be as many opinions here as there are members. So, things could feel overwhelming.
Personally, I feel making the leap of faith is easier if you start familiar and then move up to all the more heavy duty stuff later, when you feel comfortable with your decisions.
I'm not affiliated with any supplier, but I am biased to the one that finally got me to quit. I went with the KR808 model, a two-piece that emulates the look of a cigarette. I didn't have a clue about "mods" or APV's (advanced personal vaporizers, as they are now called). I just wanted familiar to start. I needed to keep the rituals while making the switch. A cig with coffee, after dinner, etc., the 808 gave the feel and ritual without the smoke and nasty 4000+ toxic chemicals.
Although I started with a respectable - and expensive - brand, someone from that forum steered me here and to another supplier, Smokeless Image. The batteries are phenomenal, lots of fun colors to choose in addition to the traditional white or black, good carts and also blanks and eliquids, too, and they just recently added an awesome "big" battery for the ATV explorers. Also, great customer service. They have great support, and don't mind talking about using other makers' liquids with their carts and batteries. They make some terrific accessories, the pcc (portable charging case) is a must have when you've make the jump with 808's.
Anyway, it is only my opinion, but I am in favor of starting familiar (even though fun with a new color), trying some sample packs of carts, and moving forward from there. I'm still using my Smokeless Image Volts (808's), even though I did just jump up to the new big battery, the X2. I still can't give up my rituals, even though I gave up the tobacco cigarettes and almost all of the nicotine (I'm down to 6mg, and some 0mg carts and liquids).
There is a lot to go through for information. Do check out the suppliers' forums for more reading and research.
