I am just wondering how many batteries everyone has. I have 2 and I definitely feel like I need more. Is it possible to feel like you have enough? I am guessing I would like at least 1 more, probably 2. Also wondering if anyone has the 3 battery charger adapter that sells for @ $85 (USD). Is it okay? Seems better than carrying 3 chargers around. I hate that it costs so much $$$ though.
