Thanks Rick & Pat.

I only entered into FF in the past several months and am still gettign to know my 5D2 and what it can do. The 5D3 would be the best single camera solution for the price, but was looking more specifically at expanding my capabilities in just the sports and birding arenas.

The 1DIV really has my interest but the lack of warranty is a small concern. do either of you have any experience with the Canon refurb store and its limited warranty?

Dan.
