The egO is great (and cignot is a very good supplier too I use them myself and the one someone quoted aboveIS for 2 complete eGos and chargers) but even cheaper is the basic 510 kit at $35 although shipping will be $5 if thats all you buy (same place - cignot - the nobox kit) and that is for 2 complete 510 basic PV.
The drawback with the basic 510 is the battery life - myself I got around this by also buying a Pass Through (plugs into a pc port or more safely a wall plug that is AC/USB) but they are around $20 (and the plugs are more $) so if you go that route you are already at around the price of an eGo kit (no Pass through with that though but you may not need one with the eGo).
Don't forget that with any PV kit you will need extra juice - although most kits come with pre-filled carts the flavors of most of them is pretty rank (some are ok but compared to bottles of juice you can refill your carts with they are rank lol)
Whatever kit you buy and wherever you buy it from you should get extra juice (not extra prefilled carts, thats expensive) because you will either get through it faster than you think or you will find the flavor of the prefilled carts doesnt suit you and you need to try something else.
Also shop around - make a list of all suppliers you get recommended and check out the reviews on them in our reviews of suppliers sections - don't take one person's word for it (including mine lol)

Check out reviews of the PV you like the looks of too, read about the pros and cons and THEN decide. I say because this tends to be an industry where impulse buying is rife - and buying a PV on impulse is often a bad (and costly) idea
