and i see lots of 510's titans,joye, scorpion, and others, and pref. or all the same just diff like bats, extras, and so on? im just worried about money really, being the bread winner for m family, with 3 kids and a wife, money gets tight. but smoking costs a bit to much ( Alot really) and shes a very addicted smoker.
All 510 parts are interchangeable. The differences are either cosmetic or in warranty - Janty makes good stuff has more of a warranty than some other places. And while I haven't tried Widow yet I should mention that site as it is a favorite run by evidently a good vendor and reportedly good shipping:
Widows Bead Work - E-cigarette Store
Get your starter kits and some extra atomizers - you get them with the Innovapor deal, and then sample some juices and find the juices you really like. You might get a passthrough or PCC or a Kensington external batt kit, but in the long run the only expense should be more juice and it won't come close to what you would spend for analogs even if you MYO (which I did for around .80/pack before the tax hike - and there's a workaround for that too...) or what you'd spend in healthcare costs.... With maintenance on attys and batts you'll spend less with replacements as well.
