If you want to save some relatively substantial storage space, convert the D800 NEF's to Adobe .DNG files...it saves a pretty fair amount of space for me! Around $1,000 seems a reasonable price for a D800; my local B&M photo store has a D810 at $1,195, and a D800 at $975. I have been pretty impressed with the D800's 36-MP files when cropped pretty heavily...it's a GOOD sensor! I'll see about posting a few .NEF's on my DropBox site, and I'll PM you the URL later tonight. I see NO reason not to own a good d-slr...the D5100 is an okay camera, but the D800 has the round eyepiece, and the full-sized viewfinder and the full-sized viewfinder screen in it, and the high-grade, $3,695 original introductory price type of build and subsystems, meaning it's a major step-up from a D3xxx or D5xxx series APS-C compact body. It has better external controls, a better AF module, and so on. To my way of thinking, the D800 is a good all-around d-slr for a Nikon shooter.
