I'm looking into buying a couple more batteries for my 600D. I don't think I'd need many as I'm not doing tons of continuous recording, but one or two might be necessary. What do people think about paying full price for Canon quality vs buying potentially inferior batteries for cheaper? Do the gains outweigh the potential quality loss.
On a somewhat related note, would anyone consider a battery grip to be a useful addition? And if so, has anyone used one?
