i think it's important (at least for me) not to see the e-cig as a single device.. To me i have
1. Batteries
2. Atomizers / cartomizers
3. Nicotine liquid
i never think of it as having a certain name of e-cig .. When someone asks me about it in person, i make it sound very simple (cause it is) and say .. Well you just buy this battery, a box of these cartomizers for ten bucks and some juice for it .. I say yeah the battery is only 20 bucks and these are ten, no big deal and they say ohhhhh really and are all amazed
i can't believe they're still selling hello016 kits with that stupid cone atomizer!!!
I bought my hello016 from digitalciggz.com and got a joye 510 atomizer with it..
The kit was $35 and batteries were $18 but they don't have them because they tell me they're waiting to reorder them because there's a new version coming out that they want to carry

keep an eye on their site because they had the best prices in the world!!
This is what i would recommend to anyone new to vaping (admittedly not having any experience with ego/riva)
1. Hello016 battery ($20-$22)
2. 510 to kr808d-1 adapter (so you can use either thread) $3
3. Joye 510 atomizer ($10 or less)
4. Joye 510 lr atomizer ($10 or less)
5. Cartomizers.. 510 e2, kr808d-1 box of each $20
6. E-liquid from trusted manufacturer.. Several flavors $30-$50
7. Oh and of course a charger $10
this way you get to try an lr atomizer, a regular atomizer, the different types of cartos... Everyone seems to prefer (end up with) a different one of those three.. You'll be staying right around $100 big ones and get a-lot of bang for your buck. That $100 will be likely to replace alot more than $100 in cigarette purchases, for sure!!
The only drawback to the hello016 i've heard is that some people prefer the airflow of the other ones.. And you can't put a cone on the hello016 unless you use those terrible cone atomizers some of them come with. The cheapest price i know of for the kit is here
the better way to smoke - hello 016 personal vaporizer, white .. But watch digital ciggz because they had them for $35!!
Anyway if one decides not to go with the hello.. Still do the rest, get you a 510 to kr adapter and box of the different kinds of cartomizers, get a regular 510 and an lr 510, try them all out because everyone likes a different one (and i like to alternate)
an ego/riva/hello whatever else with a kr adapter lets you use any of the popular atomizers/cartomizers.. It's great
