Golfers very often ask me about cameras and which one a serious student or teacher of the game should look into. I have always done well with the Casio line of high speed cameras and it appears they have come out with a real winner, the ZR200, which is ideal for anyone who wants high speed, fairly good resolution, newly introduced manual shutter speed, which had been missing from the current ZR100, and a price range around $300.
UPDATE: THIS CAMERA DOES NOT SUPPORT MANUAL SHUTTER SPEED IN MOVIE MODE, SO NO GOOD FOR GOLFERS AFTER ALL.

The camera has actually been released today and here is an in depth review on it along with all it's specs from Digital Photography Review.
An additional option is the soon to be released Kodak Playfull Dual zi12 - an excellent choice for any teacher looking to make instructional videos as it has a rare audio in jack. Ever heard those videos on YouTube with so much wind noise it wasn't worth watching? The zi12 gives you the ability to eliminate those problems and it only runs $200.
Both these cameras will provide you with the ability to view the golf swing in a similar fashion to this footage I recorded in 2011 with the Casio EX-F1:
