Hey Polar Bear, from one noobie to another, WELCOME!!!
Your getting some great advice from all of these wonderful folks at ECF!
I would definitely recommend going with an eGo/Riva battery first. Since you've already tried the basic stuff and your interested. I would save your money by not getting a Cigarette look a like. I got a blu kit and a 510 kit. Blu kits are mini 510s I believe. I gave the blu away and use the 510 as a spare. I mostly just use my Inferno (ego/riva clone from volcanoecigs.com) battery and it lasts all day.
The battery is a big choice, but IMO, the biggest choice is what kind of vaping method to use. I do suggest trying each method. Expect to lay down some cash at first to find your groove. Figure you'll spend what you normally spent on regular cigarettes the first two months. After that it should get a lot cheaper!
Dripping and Tanks are easy, they are all the same, its once you get down to cartomizers that the fun REALLY begins.
I have tried a few brands so far, mostly clear style cartomizers. I used Volcano's, which are good. Not great though.
Now I'm trying Microcig CE2 and CE3 Ultimate clearomizers. I'm loving the CE3 but they do seem to leak a little.
The CE2 clearomizers are about the same as Volcano's a bit better wick though.
I've also used some regular polyfill cartomizers and they were ok, but honestly it tasted a bit like cotton filler to me. Could have just been that brand though.
I like the style of the clearomizers, no polyfill, just a tank and a wick. They have a good throat hit and the flavor production is nice.
My next stop is to try out those Boge 2.0s everyone is ranting about here. I'm on a serious mission to find the perfect setup for me.
Juice is another big thing, it is 100% personal. So get a TON of sample sizes and don't order anything over 15ml until you've tried at least 8 different juices from 4 different juice makers. I ordered 4 30ml bottles of Volcano juice and now that I'm trying sample sizes from other places I realize I really don't like the Volcano juice all that much. Now I'm kind of stuck with 4 almost full bottles of juice. I just gave one to my buddy tonight even lol.
Any who, no more ranting from me lol. Hope you find your groove dude!
Enjoy the adventure that is vaping!
