my ego came with 2 batts but the old lady uses 1 of them. i got it for $75 at gotvapes. i really like the ego but i would still like to upgrade and size and shape dosnt matter. i would really like a darwin but cant see spending that price tag right now snice i just started a week and a half ago. all my cartomizers and attys are standard ohm ratings. would LRs help? im really enjoying vaping and can see how all of this can get really addictive with all the selections out ther.
Quite a few possibilities.
If you want to do something 'now' but for around $100
Take a look at stuff like iGo and GoGo.
Consider less expensive factory mods like E-Power (Less than $50).
Then there's the US made stuff...RoughStacks aren't very expensive and give you all sorts of battery stacking options.
Also lots of Box Mods out there for well under $50.
With all that in mind...I'd probably just pick up an extra eGo battery or two if battery life is the only problem right now. You already have a charger.........and you have several sizes of eGo/Riva batteries to choose from $15 each up.
Save up some money towards a top of the line Mod along the lines of a Darwin later.
The nice thing about Darwin is you don't have to get loads of batteries and chargers and stuff to go with it. Subtract the cost of a set of good batteries and a charger from a Darwin....all the sudden it's under $200 (still alot of money...but it should be a life-lasting, low service type of product).
Also, by the time you've set aside a couple hundred bucks or so for a high end mod...there WILL be new models out to choose from, maybe even with more competitive prices.
