Hi, and welcome to ECF. Since you have already purchased the Blu starter kit, I suggest you use that for a little bit and do some research here on ECF. Read threads about the different kinds of batteries and toppers that will deliver your
juice. Pay attention of ease of use and cost of upkeep and replacement. Some models are known for certain problems. It is going to depend on your budget and what you are looking for.
Are you actually IN Nashville? There are several vape shops in your area. Nashville Vapor on Charlotte Pike, one in the Vanderbilt Univ. area and one or two down around 4th and 8th south. Get on Google. Nothing like seeing the items in person and holding it in your hands. And you should be able to sample different juices to get an idea on what you like and don't like. This is crucial to your success.
Note that anything you buy in a vape shop can be had cheaper online. But you have to take into consideration the convenience and help that a vape shop can provide you.
Do your research here and ask lots of questions. There are many knowledgeable people here to help. I started with a Vision Spinner 1300mah and Kanger Evods and Joye 510 attys for dripping. This was almost 3 months ago and I am not smoking and am happy with my equipment. I do not need more, but I may get more. Finding a juice (
eliquid) that you can vape all day and be happy with is important. Start with sample sizes from several different companies.
There is a monthly vape meet in Nashville. I can't remember where, but it is listed in this thread. It is held the first Sunday of the month.
