A good additional microphone for my handycam?

[FoxAdriano]

Hello, can you suggest a good microphone for my Sony AX100? I need a stereo but also directional, with a switch to choose one of two options.
Mi budget $100. If it is not on the market I can buy a stereo microphone.
thanks

eBay is always a good starting point.........

I have already used eBay but I like to get some suggestions from users.

Sony ECM-MS907 is a good budget stereo M/S mic out a decent wind gag on and off you go.
