Best camcorder for slow motion playback

I want to purchase a video camera to film baseball players while batting and pitching Then want to plug it into a computer and play it back in slow motion to analyze their swings/pitching. Ease of use is a plus! I've been reading a lot on line and am getting more confused rather than less. The last discussion that I can find on this topic is more than a year old. The cameras that I keep hearing mentioned are the Panasonic tm 700, the Canon Vixia HF M31 and the Kodak Playsport. I'm a techno newbie so "plain English" would be much appreciated!! Thanks much for any help/feedback/suggestions!!
