Hi! first post.... I searched through and fond no clear response... Isn't this amazon deal a good one? Is there any catch t it?

Probably no catch, but I got the Opteka w/2 batteries for my 40D. Saved a $100.00 and had no problems.

I got a used grip and two batteries on the forum for $120.00

I just purchased a grip from Amazon. I have some issues with the shutter release and when I called their customer service department, they immediately sent out a prepaid shipping label and they sent out a new grip via next-day air. Although I like to have a good relationship with my local camera store, sometimes, they don't carry what I want. I've found Amazon to be a good vendor for photographic equipment. If you do find a problem with your order, they'll make it right!
