Hi there! I'm new to this too. I have learned a few things in the past few weeks.
1. This site is a great resource
2. I wasted my money starting with the cig style battery (808). They have a short battery life and, correct me if I am wrong, you can not use the low resistance cartomizers or atomizers. Within a few days I had bought 2 eGo batteries. I still have the 808 for an emergency, should one arise.
3. Buy at least 2 batteries.
4. Buy a variety of flavors of e-liquids in the 5ml size. (I thought that vaping anything but tobacco flavor was gross and bought too many tobacco type liquids and too large of sizes. Now I am trying to make the tobacco flavors taste good to me by adding other flavors, which is a pain when you are new to all this)
5. It is a good idea to get some lower nic strengths too, in case you want to "chain vape". It happens!
6. There is a vendor list on this site. I would suggest using one of them for supplies. Beware of deals that seem too good to be true.
7. You are starting off on the right track by hooking up with this website before deciding what to buy. I am way too impulsive and bought my first e-cig at a mall kiosk. But, I am glad that I did, as it got me started on the e-cigs and off the cancer sticks. I can't stand the taste of regular cigs anymore. Uggh!!! I've had a few when I have been having "technical difficulties" cartomizers and from the first drag, it is like licking an ashtray.
8. I just ordered an atomizer and drip tip, so that I can test the liquids I buy without wasting a new cartomizer on something that I don't like.
9. In my opinion, the DCT (dual coil tank) is a great way to go. The carts inside don't seem to crap out by burning and giving me a nasty taste, they just seem to not "hold" the juice anymore, or they just don't have the like new "sizzle".
I hope some of my opinions/suggestions are helpful to you. Welcome.
