While I don't have anything I'm looking to sell, DiscountVapers is a company I've done business with for years now and do not hesitate to recommend for people looking for more inexpensive things. The link below is for their complete kits. The only brand I prefer not to buy anymore is Smok. In my experience, Smok products haven't performed well for me and I find their tanks tend to leak like a sieve. Others my like it but I don't. My preferred brand is ELeaf, although Aspire, Kangor, VooPoo, and Joye eGo are all proven brands. When I started vaping (over 8 years ago now), my first kit was an eGo variable voltage stick battery and a CE4 clearomizer.
I hope some of this helps a bit. Good luck!
