Janey: If cost is an issue, start simple. Johnny's set up is the ultimate but you need to start small. Get a kit like this to start with: http://www.crazyvapors.com/shop/ego-ce4-900-mah-passthrough-starter-kit/ (They have pretty colors and girly designs too ) You will have to replace the clearomizers after a while. Mine last 1-2 weeks and they are $5 each but many people say they last a month or more. You will not have to replace the batteries for probably a year.
And get liquid like this: http://www.totallywicked-eliquid.com/products/e-liquid/pre-mixed-e-liquid/titan-fluid/10ml-tw-titan-fluid-product.html or http://www.johnsoncreeksmokejuice.com/shop/sample-bottles.html
This is an even cheaper option for starting out: http://www.totallywicked-eliquid.com/products/electronic-cigarette-starter-kits/tornado-tank/tornadotank-e-nic-compact-starter-kit-2-product.html
I suggest you use nicotine strength of around 24 mg if you're used to full flavor cigarettes. I even use 36 mg sometimes. The owners of the stores above will help you if you have any questions. The people at Johnson's Creek are the best I've ever dealt with. Once you have a good e-cig and find a flavor that you like, you can start upgrading later as you learn more about it. With so many options out there, it can get overwhelming.
I looked up e-cigs in your area and found this place: http://www.smokecignals.com/default.asp I don't know how good they are but it looks like they have a decent selection and reasonable prices.
It's been over 4 years since I last touched a cigarette!!! I have no regrets and I have no plans to stop vaping. I simply enjoy it.
