Need a fast motion webcame for recording golf swing

I am an avid golf fan, and want to record my golf swing to practice/learn. I signed up for this place called which charges about $1500 per 6 months. Their main service is being able to record your golf swing. Their equipment doesnt look very expensive and their software is pretty low tech. So I figured I could write my own software that could do the same thing. However I cant seem to figure out what type of camera to use along with my computer. I've tried using a few webcams, with the best result being a Logitech Quickcam 9000 pro, but I am afraid my swing motion is too fast and I cant capture the exact location of the club shaft throughout the swing. It doesnt need to be perfectly clear just somewhat. The equipment they use at the place that charges $1500 has some old cameras hooked up through s-video to the computer and the image quality is pretty fuzzy but you get a pretty good indication of where the club is, its not crystal clear but you pretty much know where it is. I was hoping I could duplicate it with some type of USB camera to cut down cost. I am guessing an average golf swing is about 2- 3 seconds. I'd probably only need like 10fps just clear frames. Do you guys have any suggestions as to what to buy and what settings to use? I am currently using 320x240 frame size and 15 fps.

Thanks
