Okay, so my dad tried the e-cig and hated it. However, he's been smoking for 37 years, and loves the taste and smell. I hate the taste, don't much like burning my throat on the smoke, and like the smell but can live without it. I really want to try an e-cig (not necessarily one by that name, but idk what else to call it). I got enough money for graduation that, even after taking care of all the stuff I need to in order to get a job and my license again, I'll have $335 left.

Oh, btw, my overall goal is to quit smoking. I've tried cold turkey, but haven't had money for (or interest in) gum, patches, or meds.

My questions are:
What (in your experience) is the best "e-cig"?
How do the different types compare in prices? (This includes the cartridges)
Do they have any "contracts" where every month they automatically deduct a certain amount from your credit card and send you a certain number of "juice" cartridges?
Is there any way I can buy one without a credit card?
Most importantly: How well do they work? Do you get a nicotine buzz? If so, is it equal to, more or less than that of a regular cigarette, nicotine gum, or nicotine patches?
And anything else you feel is worth mentioning, as far as looks, convenience, weight, etc.

ANY feedback will be much appreciated!!!
