I'd reccomend an aerotank V2 as a starter tank. Great ease of use and nice throat hit. I used mine with a vision spinner battery and was happy with it. Youtube is your friend, there are video reviews of almost everything you can imagine on there and you can see if it is something you can get on with or if it is too fiddly for your taste.
I'd just say use the tank when you can but have a cigarette when you feel like you need one. I was on my tank for a lot of the day but had a couple of fags when I got up and when I went to bed. I got used to the tank and stopped using the fags naturally. For the first month I carried a tin of rollies round with me as a comfort blanket but slowly realised I wasn't having any. Had a mad urge for one the other day so had one but found I didn't enjoy it at all.
This should be fun as much as healthy and swapping from one to the other should be a natural progression more than a punishment. There aren't vape police wandering round to give you a beating if you smoke a cigarette now and again, it is up to you how fast or slow you swap over, and if you don't swap completely and still have the odd fag then don't think you have failed, think how well you are doing cutting down. No fags is best, but cutting down to a few a day is still an achievement that will have great health benefits.
Everyone on here has had the same experience of feeling overwhelmed with the amount of stuff available. There is no right way or wrong way, just go with what feels good to you. Think of the forum as a fun and sometimes very silly version of Alcohol Anonymous without the guilt or the god bothering. The members will give you lots of advice and the vendors are great at telling you what they sell and what might suit you rather than trying to sell you the most expensive stuff they can that you might never use.
