Used Nikon D3 in excellent condition can be had for under 900 usd . Thing of beauty. I found one a couple years ago for under 800, fabulous camera. I now have a D5 but I can't let go of the D3. Truly a groundbreaking camera. No video junk, drives like every Nikon pro camera made since 1959. Find one with less than 50-60,000 clicks on the shutter. Mine only had 8,000. Aftermarket battery packs are cheap now and they work fine. Built like a tank. 12 MP is plenty. MHO
I have a D700, and I just bought a D300 for $39.00 The fact that everyone chases megapixels and ultra-high ISOs is such an advantage for those of us who don't (maybe I should keep my mouth shut).
The OP said he never prints more than 8x10. Just to provide some perspective, if I touch my nose to the 60-inch screen of my 4K TV, I can barely make out the pixels. A 4K image is around nine megapixels, so you could print a 60-inch image, bury your nose in it, and be happy.
If you enjoy cropping instead of composing, that's a different story. It's certainly impressive to be able to crop off half the picture and still have 18 megapixels left, so I understand the desire, if you have the money. But to be able to buy a professional caliber camera for a few hundred dollars is astounding. Think of all the money you get to keep and spend on something else!
