Grats on 7 days off analogs!
I got this ego-c twist VV kit for my first kit this week:
http://bombvapor.com/index.php?option=com_virtuemart&Itemid=66 comes with 2 clearomizers that work pretty well (but do not have replacable coil/heads) and a 10ml bottle of juice (I got apple, and it's pretty tasty, but does not compare with some of the higher end juices I've gotten at other vendors). For the price, it was the perfect starter kit for me, and you'd be able to have a backup. I'd recommend extra clearos or cartomizers if you want to try that route, so you can have multiple ready with different juices ( a week in and I've got 5 clearos filled with juices I like out of 10 juices bought).
On an associated note, I did have a problem with my product (due to Chinese mfg standards!) and bombvapor.com did me a solid and replaced my whole order, very quickly, as well as being super polite and responsive when I was kind of an annoying customer. Some of the best customer service I've ever had with an internet vendor of anything.
If you MUST upgrade and have a very low price point,
Katana Kit these Katana Kits are great starter kits. They are without Variable Voltage. VV can change everything about a juice's flavor/vape cloud/throat hit so unless you're totally pressed for a cheap kit, I would recommend against this kit.
If you've got a higher price point, this is my first upgrade I have planned:
BlackWidows VAMO (Full Kit) - Advanced Kits : Black Widows Vapor .com which is the cheapest complete kit (2 batteries and a charger!) for a Vamo that I've found with extensive searching. Also the only decently priced black chrome. For comparison, here's a chrome version
cheapest vamo mod vv vw starter kit that comes with no clearos or other atomizers and no fancy "gift box".
Enjoy my huge amounts of research for newb kits.
