I'm wondering if anybody has any experience with the third party batteries being sold currently on Ebay, or if you would recommend to simply stick to Panasonic batteries. I've read that the 3rd party ones don't show their charge on the LCD display? How bothersome is this really? Does it matter to you or it makes no difference? The original battery is being sold currently on Amazon for almost $50 while the copies are selling for anywhere from $9 to $22. My wallet is telling me one thing and my heart is telling me another. Opinions please.
