Okey doke, I can wait a little longer

Thanks for the honesty... oh, and just FYI - how expensive is the setup per e-cig? I like to run with a rotating set of 5 (I have a 5 bay charger as my main charger, then others for car, etc.) Do you recommend buying just one to get a "taste" first, or just going whole hog?
The attys I've been getting lately for the 510 keep dying on me fast... just started happening a month ago, and never happened prior (I was getting a good two weeks out of them previously), so I'm open to a full switch... but if it's crazy expensive upfront, then I may have to piecemeal it. Thanks again, and looking forward to it...
oh, and one more thing... I LOVE the 510's size. Not to big, not too small. It's why I never bought one of those big honkin' batteries, I dont mind switching, as I always keep a spare in my pocket, and a full array of fresh batteries on the charger... does this change the recommendation for the GGTS?
