Come April it will have been one year since I stopped smoking, all due to electronic cigarettes.
I now use '801' electronic cigarettes (the number refers to how long they are in millimeters). They give great 'vapor'.
A couple of links:
One, virtually all electronic cigarettes sold in the USA are made in China. For the past 8 months I have been purchasing from a Chinese company, called Heaven's Gifts. Very fast shipping (I usually get my order within a week). Much cheaper prices than buying from most USA companies.

In addition to the 801 (which they sell) I also have been using the Joye Stick, which is a strange little device that uses an
AAA size battery (although not quite the same size). Produces beautiful vapor, plus you use the 801 atomizers in it.
Be sure to buy 'blank' cartridges (for whatever type of e-cigarrette you buy), and then use your own juice. I buy most of my e-juice from Johnson Creek Smoke Juice

My favorite is the Mint Chocolate. I recommend buying the 'sampler' (called "Welcome to e-smoking kit" for $39.99). You get 10 small bottles of different types of juice, plus other accessories. I get the 'medium' nicotine content (you can get no nicotin, low, medium or high).
Finally, a good website to simple read about electronic cigarrettes:

I also contribute to that board under legalsea. Look for the thread that has photos of the various types of e-cigarettes.
Good luck and let me know if you have any more questions.
