The BG E2 grip fits the 40D much better than it did on my 30D Do you need one Its a choice you need to make I love mine and its really nice for holding the camera for vertical shots it also balances out with my L lenses would I pay extra for the BG E2N grip No its not worth it for that piece of foam if you need that go to a hobby shop get some and install it yourself and pocket the savings
Cheers glider, yeah i def need one - biggish hands and heavy lenses
and i have one on the 5d and wouldnt be without it. im not fussed on the sealing - the batts from stirlingtek are only $10 and should it get in the drink i dont think the grip will be my worry.
Like Gliderparentntn said, it fits the 40D alot better than in did on the 30D. It seems to fit "tighter", which is a good thing. The BG-E2N costs $100.00 more and the only difference is a little piece of foam on the battery door. THERE IS NO AF-ON BUTTON ON THE BG-E2N! I personally would have paid a hundred bucks extra for that. Here is mine (pretty nice, huh?)
I was thinking the same.... if it was functionally advanced - but it aint so looks like the old model for me... 
Cheers potn'ers
