Buying a rechargeable electronic cigarette will be MUCH cheaper than buying disposables.
And buying bottles of juice to refill your electronic cigarette is MUCH cheaper than buying prefilled cartridges.
And if you are really motivated, making your own juice is MUCH cheaper than buying it.
I am not that motivated, and never will be, but many just love making their own.
As long as the size doesn't bother you, I would echo the recommendations for the Ego Twist battery.
The hard part is going to be figuring out what juice delivery method you want to use with it.
When I think about it, I do want something that's not so cumbersome that I can't take it with me to bars or nightclubs. But on the other hand the eGo seems like so much of a logical choice that it may be worth it to buy an occasional disposable if need be. BUT... on the other hand, all I need is something to get me off these analogs for good. The disposables work (kind of... I'm drinking now and it's pushing my analog cravings) and if there's a rechargeable cig around that can do the trick I'm fine with that... but on the other hand it seems that everyone winds up moving away from those... lol I don't know it's still all so new to me but I'm taking it all in...
I've watched a few youtube videos and I must say that a lot of the eGos look really sweet, larger than an e-cig but really sweet, and the vapor clouds are nice too...
By the way, when you say juice delivery are you referring to carthos vs clearos? I'm still trying to learn the lingo and what is what.
