I use a MTL device, at 15 mg nicotine and that does the trick for me. I agree with Trigster about what appeals to you from some of the major brands.
You do need to decide if you want to inhale less clouds of vapor in a smaller, higher nic device, or blow large clouds on a DL sub0hm device. It can be hard to tell if you are going to prefer one or the other. The pinned links in this forum:
New Members Information may help you get started, and I'm sure Brother Bob, who kind of watches over this forum will be along to provide more helpful links. You really want to read up on types of device and try to see what appeals to you most. If you have a B&M near you, it might be a good idea to go in and actually handle some setups and ask questions about them. You don't have to purchase any of them, but it might give you a better idea.
Best of luck, I too was "ready" to quit when I got here, and even though I started out with a device that was all wrong for me, I was able to replace it with something more suited to my needs...
Welcome to ECF and congrats on your desire to quit smoking.
