I recently picked up a Nikon EM for $20. I really like how lightweight and simple the camera is. It's aperture-priority automatic only and that's what I shoot most of the time so it works perfectly for quick snapshots. I like that it "beeps" quietly if the shutter speed is too slow or fast, and the one-button "backlight" compensation is quick and easy.
As with most/all of the more compact and simple cameras in Nikon's non-pro lineup, my only hang-up is the ~92% viewfinder. I really like having exact 100% viewfinders, but alas I will always have to use one of my F cameras for that.
