5D grip
When I had the 20D I bought the grip. Now that I bought the 5D, I had to get the grip again. along with the canon leather strap, this makes a very handy and usefull accessory when shooting weddings.

Canon BG-E4 Battery grip for EOS 5D Digital SLR Camera
Ergonomically its superb for vertically composed shooting. Feels solid and sturdy. For travel in remote areas where power outlets are scarce the 6 AA battery option addresses that issue, this is the main reason I purchased the grip. As far as ruggedness goes, I'm taking it back to Alaska this summer and down to Nicaragua so I'll update this post after I return. The camera feels significantly more sturdy and "balanced" with the grip attached when used with the 24-70mm f2.8L and 70-200mm F2.8. For situations where discretion is required, the extra size can be initimidating for you potential subjects. The price seems a little steep.

necessary, but it is Canon and you pay for the name
I think the grip is a necessity. It changes the whole feel and balance of the camera for the better. You also have the advantage of running off of two batteries with twice the shoot time without changing. Over $200 for a glorified battery holder with 50 cents worth of electronics is tough to accept. There are Chinese knock-offs that are half the price but I guess if you are going to spend over 2 grand for the 5D camera another couple of hundred for the Canon name (quality?) should not even be a concern..
