Looking to upgrade my body, i currently have a Rebel XTi, mostly want to upgrade for a faster frame rate, 3fps is too slow. Looking at 30D or possibly 40D, Even a used 40D is still out of my price range at this point, was curious if anybody found the 6.5 fps to be that much of an advantage over the 5 fps of the 30D. I like shooting any sports but spend most of my time at baseball games due to cheaper tix. thanks in advance
