It does not matter. Just make sure you buy from a reputable photo store like B&H, Cameta, Adorama, or Canon/Nikon Stores. That way you're not likely to get a gray market body or lens. You'll save money getting refurbished. The only drawback, is that if you buy Nikon, you will only get a 90 day warranty. Not a big deal to worry about. IMO.
I've had both, and it really does not make a difference. If you buy a refurb body, and it is available at time of purchase, consider an extended warranty for the peace of mind.
