In Adorama's defense, they're a business, with lots of overhead, and need to make money off of their time and liability on the equipment.
Are those D750s you mention on ebay "selling" or "listing" for $1200?
And remember you'll pay ebay 10% and paypal 4% of the sales price, and the shipping costs!
So if you "sell" there for $1200, you're only going to see about $1,035.
Follow the "for sale" page over on Fred Miranda, they will keep up the items sold for some time so you can see what things are really selling for (prices go away after about a week though). If your equipment is in well cared for condition, US models, you'll get some good return there. Big swing in prices based on those details as well as number of actuations on a camera body.
http://www.fredmiranda.com/forum/board/10BTW- I've been looking for a full frame Nikon, trying to decide between the 750, 810 or new 850. From what I see decent D750s are going for around $1000 on both Miranda and ebay, unless they are "like New" and only have a couple thousand clicks.
Wish I could make you an offer, but I need to wait until late November for some business/inc reasons. Good luck.
