Just received mine today and will be playing with it in the days to come. One question, Does anybody know where I can get a battery door for it? It came with the BG installed and the door was not stored in the stowage receptacle in the grip. I like the grip with the L lenses but it's kind of burdensome with smaller glass so I would like the option of shooting without the BG in place. I can't post a wanted ad until I have 30 posts. Does Canon still carry this part?
Just search Ebay. There are a bunch of them (around $13-14).
