Latest acquisition was earlier this month. A nice clean F5 for $250. Traded three pre-AI Nikkors that I had lying around, plus a flash and some other small items for it. Got the cost down to $125+tax. Was able to keep all of my Nikon bodies, which is unusual for me. Usually wind up trading something away, then replacing it within a few weeks with an identical item (or the exact item that I traded away).
With respect to the Nikkors, they all were duplicates of what I already owned. I try to get pre-AI Nikkor lenses that can accept an AI conversion ring. The 135 I traded was a little too early to have a ring available for it. The 28 was a donor lens, sourced for the AI ring that was installed on it. Same with the 50 that I traded away.
