In 2000, when I was buying my first “real” camera, I bought a Nikon Coolpix 990 camera. I played with it for about four hours, then I returned to the camera store and begged them to let me return it. Thankfully, they did. But ever since, it was kind of “the one that got away”.
I went off and bought a N60, which I used for about 4 years before buying my D70. Seemed like a great upgrade.
(I also had a FM10 that I shot with B&W for another 4-5 years after that, until I lost my darkroom space.)
Anyway, I was in a camera shop and saw a fairly good looking copy of a 990 for under $5, so I got it, and I’ve played around shooting with it a couple of times. It eats through AA batteries like they are going out of style, so it appears to be working correctly. 
Old digital cameras can be a lot of fun!
