Find a shop and pick up an Ego cTwist battery (or 2), an Aspire tank (with a pack of replacement coils) and a bottle of juice at 24mg of nicotine (more than is needed, but the transition from cigarettes takes better, IMO). Sample the flavors. The batteries are about $25 each, the tank is about $10, the pack of coils about $13. Juice depends, but a 10ml bottle is about $10 and a 30ml is about $22 in my area (Eastern WA). Sample the flavors until you find one you like. Oh yeah, you will also need the usb charging cord, roughly $7.
Don’t buy the starter kit. The batteries are under powered and you will find that they simply don’t produce enough. And avoid the wick style tanks/coils. They gum up and lose effectiveness quickly.
Some of the cheaper Aspire tanks and coils work very well and are inexpensive.
