Okay...do you want to plug the mic into a camera or are you going into your computer?
If it's into a camera and that has 3.5 mm connectors then you're stuck with getting a mic that can go that way.
If you're going into your computer, you have other options.
Way up above somebody suggested a lav mic and for simple video work I think that suggestion was spot on. Lot's of lavs cost hundreds of dollars but just lately I've been buying some cheap Chinese lavs for radio mic use and I've been pleasantly surprised at the quality for the money.
The mics I've been buying are from
THIS EBAY OPERATOR. I've placed a couple of orders and they've been prompt on their deliveries and seem pretty above board.
From their range, you have a couple of options. If you're going into a computer, buy the black clip on with an XLR connector that can run on phantom power, then take the money you've saved and buy a USB interface like a Focusrite Scarlett 2i2 or M Audio M Track. Either would be day and night ahead of trying to go into an on board sound card.
If, on the other hand, you're going into a camera, check the connector you need and whether your camera provides a bias voltage for an electret mic--most do. If so, just order a mic with the right connector. If not, somewhere on that site is a bias voltage adaptor for their basic mics.
One other thing...they list a cheap shotgun. I have no idea if it's any good or not so if anyone buys one to try, let me know how you get on!
