I have had the N80 for a few months now and love it. If you want to record exposure time you might try to find an F80s, they can record the exposure between the frames of the images. Its a grey market(imported through a third party) camera but I know B&H carries them, and B&H offers some warranty since you don't have Nikon's warranty on grey market cameras. I know there is a huge debate over grey market equipment but if its a camera thats just not offered any other way I don't see the problem.
