Cheap but good stereo mike for Sony A6300 camera, any make so long as it fits.

[Redspider]

I have looked for a stereo mike & they can be very cheap or very dear & I have no idea if any are good or not. I see this mike 'Rode VideoMicro Compact on camera Microphone' get's good reviews for around £37-00, but is mono. I appreciate you can pay hundreds to get a good mike, but I won't use it enough, so is there a cheapish but good stereo microphone anyone can recommend? Thanks for any help.
