Hi scott, welcome.
It is sort of an up-front investment. If you go for Riva (Liberty Flights) or Tornado (Totally Wicked), it is practically the same thing (as well as eGo). The are all 510-threaded, which will give you future possibilities for trying out other delivery methods. What comes with the unit (atomizers + carts) is ok for a start, imo. I have not heard of many (any?)regretting to start right off with this type of equipment (w/ Manual batteries). You can't go wrong.
Juice is also important, and subjective. I started with TW M/boro 18mg - although on the expensive side - it is a tobaccoish and some sweet and pleasant. 18mg==1,5 pack/day. Other TW (Decadent Vapor) are also good (and expensive)
You can stock some 24mg juice for "emergencies". LF also stock some good juices, I don't have personal experience. Many like RY4 (sweet) and 555 (a little nutty). YMMW. I'm not sure how customs will treat any international shipments - I mostly use uk sites due to our customs... Inside eu there are no customs problems.
Good luck with whatever you decide, and do keep asking questions.
