In general Rode mic's are good starters. THIS ONE is in your price range.
A good mic will last longer than your camera. When you can afford it you
should upgrade to a mic that will last you for many years. An excellent
Sennheiser set up (around $450 all in) will last more than 20 years. That's
About $20 per year. I'm using a Sennheiser that I bought in 1985.
If you are going to mount the mic on the camera a shotgun mic is your worst option. The Rode VideoMic GO is a good option for you, as is the the Rode VideoMic and Rode VideoMic Pro, as they are all supercardioid mics.
Just curious - why do you say that mounting a shotgun mic is the worst option?
Because of the polar pattern. Shotguns need to be very precisely aimed. If the mic is mounted on the camera the best looking shot may be the worst sounding position for sound; you could end up recording whatever is coming out of the subjects ear or whatever is over their shoulder. Supercardioids and hypercardioids are the best options for camera mounted mics.
