Hello everyone! I'm going to buy either the Canon xti or 30D. The problem I have is I will be using this camera for my son's baseball games. He's a pitcher and I was wondering will three (3) fps be ok for capturing the entire wind up or am I better off going with the Canon 30D at five (5) fps? It would be nice to save the additional money in buying the xti but if I must I'll buy the 30D. Thank you.
