I found these through a video on YouTube and couldn't believe that the guy was getting decent audio out of them. I bought a two pack for $2.88!! That's $1.44 per mic...
Anyway, for an extremely inexpensive mic, I'm very pleased with the performance compared to the onboard microphones of the FZ200. I got this camera to do some blog work, but was not impressed with the audio.
This might make it tolerable. See what you think.
