OK - one more post and I'll stop, I promise

There is tons of information to gather when you are first starting, so just pace yourself and educate as much as possible. Jump in and buy something - I promise it will work out okay. You will have to buy more clearos eventually, just like Ocelot said. I personally bought about a dozen of a couple of different types when I started so that I could figure out what folks meant by the top coil experience vs the bottom coil experience (I like bottom coils mostly, for example). If you get something to start, it's a good start...you start to learn what you like or even what you don't. If you don't vape a lot, you won't need juice right away. I bought about 100ml to start, and it lasted me about 6 weeks. If you end up vaping more than you thought, no problem - buy more juice (it's an experimenting opportunity! Try a new flavor you think you might like with one you do like) and it will still be cheaper/better than analogs. I also don't think you can go wrong with an ego twist - it is incredibly versatile, and I still use mine often eventhough I have branched out to more "advanced" pvs.
Edit: you could also consider coming to Vapefest NY on Long Island (I think March 23 weekend). You will get to meet some vendors, some fellow vapers, and look at all of this stuff in real life.
