I'm such a cheapskate. I bought an "as-is" F3. It actually works, but the meter is a little off, and the light in the finder doesn't work.
I found these instructions via DuckDuckGo, but didn't think it would work for me because it didn't feel like my button depressed at all. I tried it anyway and, surprise surprise, it worked! It's really easy, if you want to give it a try:
