FWIW I got the cig-a-like to start. 3 days later I sold it to a coworker, too much charging, too much refilling, not enough good hits per charge..
They aren't for most people but some like it. He is still using it most of the time, but he also got an eGo Twist for when he wants a bigger bang (or when the tiny batteries are both charging..)
I'd suggest finding a reputable vendor and assembling a basic starter kit. (I've got experience with vapedojo, mypvshop and myfreedomsmokes. You should be able to get it all from either of the latter two.)
- Prefilled "Cartomizers". Get a variety of flavors and strengths if you can, and since they are prefilled it takes most of the trouble. (Don't throw them away though, they are refillable.) This is similar to what Blu or N-Joy use, only better..
- 650mah+ battery ("eGo" has both standard types of connector)
- Spare battery (can be the "cig-a-like" style at 350mah)
- Charger for batteries
- Carrying case of some sort
To upgrade that to a less-basic kit:
- Spinner or eGo Twist (lets you set the voltage to whatever you want so you get the same hit every time)
- CE4, CE5 or Mini-Nova tanks (skip the normal Nova until you have juice you really like)
- Raw "juice" in different flavors (sample packs are great for this)
(Alternately, check out the dojo
starter kit. $13, just add in some juices at $5/10ml and a spare battery and you are good.. It is fairly small but doesn't look like a cig.)
The basic kit will give you something that can look like a cig (or a Blu) as well as a larger battery in case you plan to use it for more than 1 hour out of every 3.
You mentioned durable, but nothing here is going to be super durable. You can drop most of it but you can't run it over or sit on it. Lots of plastic, lots of (relatively) weak thread-joints, etc.. (The full-size Novas from vapedojo.com are metal tubes instead of plastic, but they hold a LOT of juice. Not good when you aren't sure on flavors yet..)
As far as actually quitting, I switched over completely as soon as my batteries were charged. YMMV..
Some tips though:
Don't approach it like "something you do during smoke breaks instead of smoking". It doesn't work the same at all.. Instead, think of it as something you do pretty frequently
between breaks AND something you do during breaks instead of smoking.
With that in mind, I'd suggest a pile of 16-18mg juices and a couple of 24mg. You can hit the 16-18 as frequently as you want (every few minutes or more) without getting an OD headache, and when the desire to smoke starts to come up (you are looking at the clock, out the window, patting your pockets for a pack, etc) switch up to 24 for a bit and let it fade..
