I'm new too so I'm liking all the comments that you are getting because it's very educational for me as well. With that said, I bought the joyetech ego kit for my first starter and about 2 months later realized I was somewhat outgrowing it. I upgraded to the vamo and love it. You can leave a section of the battery out. Basically it has 2 batteries and the whole middle section can unscrew so you can run it with just one battery which makes the whole unit much smaller. I bought on amazon 2 replacement batteries for like $10 which actually came with a plastic carrying case for the batteries that holds 4. Being female, I felt that running it on the "shorter" version looked less dramatic if I take it out in public. It doesn't scream "hey look at my GIANT ecig!"
My fav tank that I use is the protank. I have several of these and they fit my vamo and my ego but the protank mini I think fits the ego better and doesn't feel top heavy. This was just recently released as well and I honestly can't find anything wrong with this thing other than price. But, I have yet to have one leak on me unlike my other clearomizers etc.
I have the vamo 2 but pretty much a month later there was a vamo 3. I also bought mine in a store locally and probably overpaid by $25 from what I can see online. The vamo 3 in black chrome seems AWESOME. I try not to have buyers remorse.
Also, I was going to local stores initially to buy juice but I almost feel like now some of it is "junk" compared to what I have ordered online. My fav juice sites are virgin vapor and from there if you like cotton candy, you will flip over theirs. I also favor the going bananas flavor - it's seriously the best banana I have ever tried. they make a great chocolate/tobacco blend I think called dark side of the moon. And I'm digging their orange creamsicle.
my second favorite place is mt baker vapor. You can request extra shots of flavor to ramp it up.
I hope this helps! I've learned from trial and error but there are things on the equipment side that I wish I would have known before. From a juice side, it's all about trying it out I think.
