I just got my VaporKing from V4L today, and find that that has been a good product and easy to use for a beginner, like myself. Just two pieces for it, and I figure I'll order some liquid for it soon, as I see that the cartomizers can be refilled for a couple of more uses.
Definitely recommend the KR808D-1 from vapor4life and others or the 510. Other models simply have less users overall and get less support, and I believe that is the case for good reason.
