Jessy: Welcome aboard, while I encourage you to research all you can, I also caution you at times it may seem overwhelming. If you reach that point try to take a break from reading everything you can find). My first exp was with Smoke51 , we bought this based on the theory that the local store would support it, the cartomizers would be easy and no mess. We found that the carts did not last as long as advertised ( actually no where near as long) and we had to recharge batteries often. After some research and appropriate amount of lurking here I finally bought the Screwdriver
The ScrewDriver Online Electronic Cigarette Shop on that link you can also find a forum dedicated to the SD. These where quite a step up for us and a just a bit of a learning curve. I have found I much prefer working with juice, I have allot more control over flavor etc, and it is really fun. My husband tends to be a bit fussy and hard to get on to new things but even he is coming along well with it.

Very kind folks here did point me in the right direction to purchase lower cost carts for my Smoke51 but I decided to go further and get into the mods. As much as I love my SD I might not stop there, now I am dreaming of something with a PT or maybe a Chuck(another mod). There are also enough video reviews on utube to boggle your mind, have fun and watch some of them. ECF is an amazing resource, if you have a question, most likely someone here has the answer.
Please take time to sign the petitions if you have not done so already.
Good luck, have fun and ask away if you cant find what you are looking for with the search function.
