D80 doesn't take the D40 battery so buy another EN-EL3E batter. You can get 3rd party batteries buy Nikon tends to be recommend brand for nikon cameras. Just wanted to let you know on the battery situation.

D80 body can be had for under 900 USD. B and H and adorama dont accept or ship orders on sabbath but on non sabbath days they are super quick. They are the cheapest Legit online camera retailers out there. I ordered 2 CR-P2 batteries for my grandfathers Pentax SF1 and it came very quickly with UPS ground. Hopefully when you get your new camera enjoy it!
