I thought it was a nice thread title

Anyway, right now I'm looking for the perfect lens (in ratio w/budget) for sports photography this fall. I've done a fair amount of research and in doing so I've changed my mind plenty of times. By the time I'm ready to buy the gear I'll have $2,500 all dedicated to sports photography.
I was first set on the 70-200mm f/2.8 IS and then I came across the Sigma 120-300mm f/2.8 and I've gone back and forth between the two. I've seen amazing things from the Sigma - in my opinion the images "pop" a lot more than the Canon and the reach @2.8 is invaluable, but the problem is that I've also heard bad things about it - concerning AF and quality control.
Right now I don't know which one to pick and it would be helpful to hear peoples .02cents and advice.
Sorry if this same question has come up before
