Hi Gina - look for something like this.
eGo Variable Voltage 650mAh Battery - Stainless w/Rubber Button
Kanger T2 Clearomizer - Blue - 2.2ohm - Long Wick
Kanger T2 Innard - 5 Pack - 2.2-2.4ohms - LONG wick (out of stock right now at this vendor, but you get the idea)
USB Wall Socket Charger - 500mah
eGo/510 USB Rapid Charger - 420mAh
I'd personally recommend 2 eGo Twists, 2 Kanger T2 clearomizers at 2.2-2.4 ohm, some (5 maybe?) replacement head/coils for the T2's.
The T2 clearomizer is super easy to fill, and is also super easy to change out the heads/coil once its burned out and replace it with a fresh one.
In addition the T2 is made specially for the eGo Twist, so leaks are much less likely.
2 chargers and then sampler packs of juice.
The above are the easiest and most reliable "fill n goes" for us folk who don't like fiddling about with this n that all day long.
Next the juice hunt: If you smoked a pack a day. order three different percentages of nicotine - an 18 for regular use, a 24 for "I NEED A CIGARETTE OR ELSE!!" use and a 12 or even 6 mg for night use (so you can get to sleep better)
The juice: Check out various vendors on forum. Stick with the smallest size bottle or sampler packs till you know what your preference is. Juice has 2 to 3 components - nicotine percentage as mentioned above; PG (propylene glycol) and/or VG (vegetable glycerin). PG accentuates the flavor and (along with nicotine) the throat hit. VG creates lots of vapor.
Order 1 smallest bottle of the flavor that appeals to you in 80/20 PG/VG, 1 smallest bottle at 50/50 PG/VG and 1 smallest bottle of 100% VG.
Why?
Some people are sensitive to PG or VG. You won't know which you prefer until you try them in varying ratios.
And finally - drink lots of water as both PG and VG will dehydrate you.
Hope that's of some use. Good luck
