Amy,
You seem like a really sweet person. Welcome to the 'easy way to be an ex-smoker' club.
In one of your threads you mentioned not spending a lot of money.
E-cigs are a strange deal. As someone else said, "you trade a habit for an obsession".
I say this because in 6 short weeks, I did move through several devices to seek my goal of performance, reliability, and convenience.
If a $100 device looks to be your answer, and they are a supplier on this forum, then its probably going to be a good purchase for you. This forum can help substantiate any questions you have about a product.
Otherwise, the cheap route will have you temporarily satisfied, but soon enough, disappointed.
Consider some of the 10 minute reviews by Grimmgreen.com as well as other.
I personally took the route of a Reo mini. A small box with a bottle of juice that lasts all day. A quick squeeze of the bottle shoots some juice into the atomizer and its good for a few puffs. I haven't found anything simpler or better in performance.
I was hung up on the idea of not having a device that was a ciggy-like cylinder. This hang-up quickly passes.
Good luck...and quit drinking the juice!!
