Hi all, Im still fairly new to all this and was hoping for some advice. I am expecting to recieve a newly bought GH2 this week and I was thinking of buying an extra battery for it but i'm having issues trying to decide on whether or not I should buy an OEM Panasonic Battery or just opt for one of those aftermarket batteries that are normally found for a few dollars cheaper. Naturaly i'm inclined to think that buying OEM is always better but the budget is tight these days and I could sure save a few dollars here and there. From anyones experience, is there anything I have to worry about when deciding on what brand battery to buy or does it really not even matter? Things that im worried about are pretty much battery life, and charge. If these aftermarket battieries perform just as good as OEM batteries, I might as well just save some money and get one of those. Thanks in advance for any recommendations or suggestions.
