Unless you are absolutely certain that the camera will meet your needs, you might want to consider checking the retailer's return policy. As an example, Amazon's return policy applies only when ordering directly from Amazon, not one of its merchants.
I ordered from B&H because, in the event the camera doesn't meet my needs, I know they honor their return policy. I needed a digital projector awhile back and could not decide which one would be the best simply by reviewing the specs; I had to order two of them and try them out side-by-side. I called B&H to ensure that it would be acceptable to order both projectors, knowing that I would return one of them. The person responded that, "Yes, that's one of the reasons we have that policy." So, I ordered both projectors, returned the one that didn't meet my needs, and B&H credited my account right on schedule.
