For a new vaper, I would suggest starting out with a good clearomizer with easily replaceable coil head assemblies.
Take some time to get used to the ins and outs of vaping before getting into rebuildables and not jump right in with an RDA.
There is a reason that most sites have RBAs and RDAs highlighted with a phrase something like "For Experienced Users Only".
I agree. Keep it simple at first. If there's too much to learn right away, it might turn you off. Also, wrapping your own coils and all that can have serious safety implications that are best avoided until you get to know what you're doing.
Find a juice that you like. I think that, as has been said, is the most important factor in making vaping stick. As you become more used to it, get a device that's a little more advanced and get that much more flavor out of the juice you've been vaping. It's kinda like rediscovering vaping, even after doing it for a while.
If you're into stats, or need encouragement, find a signature banner that keeps track of your progress. It's helped me immensely.
I tried all this in 2011 and it just didn't stick. Partly because I tried it with cigalikes (I suggest ANYTHING but cigalikes), but partly because I just didn't have the internal or external encouragement.
There are many, many possibilities with vaping. Start slow and small. Get to know what you can handle, and take on more and more little by little.
Good luck, and congratulations!
