Hey guys,
Ive been looking into getting a battery grip for my 40d. I went years without one on my 20d and after borrowing a friends camera equipped with the BG-e2 im sold. The question is whether to just buy the canon brand one or go generic.

Heres one listed on Ebay

Im not opposed to spending the extra cash for the real deal....im just wondering whether its really necessary?

Thanks

Jeff
