Main question to ask you first? How important is it that your batteries look like or be the same size as a cigarette?

Size comparison of 3 ego batteries (white) and two cigalike batteries next to a cigarette.
As someone already pointed out, the "cigalikes" have gotten many smokers off of cigarettes successfully. However, because of their small battery, they only hold a charge for 3 - 4 hours each. That means needing a few of them available to last out a day, and spending your evenings recharging them. They also are limited to just a couple of juice delivery devices (the parts that hold the nicotine e-liquid and produce the vapor).

Going with the larger "ego" size batteries will increase battery time from 6 - 13 hours depending on their length, and opens up more options in juice delivery devices. This would be the option to use various types of "tanks" which allow larger quantities of juice to be used without the need to refill them throughout the day.

Whether you go with the cigarette size batteries or the larger ego size batteries, you will need to have multiple batteries, a charger, an usb/wall unit to use the charger away from a computer, and multiple "toppers" or juice delivery devices to use on the batteries. The juice devices only last 1-3 weeks each, so you need extras.

You will need e-liquid containing nicotine. This liquid comes in different strengths of nicotine depending upon how heavy of a smoker you were. A typical 1 ppd smoker will require 24 mg strength nicotine.
These come in a variety of flavors, just don't expect one to taste like a tobacco cigarette, there isn't one. Although e-cigarettes mimicks smoking in some respects, it IS different. Regardless of the flavor(s) that you end up with, you'll still be getting the nicotine you need from the vapor. Try a variety of flavors until you find some favorites.
There are sometimes options in the blend of liquid used as the base (Pg and Vg), starting off just get the 50/50 pg/vg if given that option.
Most vapors consume 3 - 6 ml of juice a day, so figure appropriately when ordering or purchasing juice. Juice flavors are very subjective in what one person may like or dislike. I recommend getting several smaller size bottles in different flavors to determine what flavor you will like, and later purchasing a larger quantity once you've found a flavor you like.
