I am also one who started with Green Smoke and they got me off analogs so I can't say they are all that bad. True there prices are hihg but if you do some research you will find that the battery they use is the E9, aka 808D-2 battery which can be bought else where for about $17.00 via LeCig
LeCig Electronic Cigarette Store also the sister company of Vapure (They tyoo use the E9 battery) e-juice sells the batter for about $15 and you can find the unversial charger at LeCig for a fraction of the cost of Green Smoke and it also works with the KR808D-1 battery too. So price wise I would say they aren't anymore than any other place if you shop around for Green Smoke's hardware elsewhere.
In the end, whatever place(s) you find makes you happy and they actually work for you - then I don't see how anyone can complain. Be happy you managed to get off the cancer sticks. I still use Green Smoke along with my Vapor King from Vapor 4 Life.
