I'm looking for a high quality lens for my Canon T2i DSLR. I'm pretty much looking for a macro/zoom lens. Something I can take to an NFL football game, sit halfway up the stands, and get clear close-up pictures of players and plays. Somewhere around 70-250mm minimum. I'd like to find 300mm+ if the IQ is there and the price remains reasonable. I'm looking for a lens right around $500-$600 and I wouldn't go a penny over $1000. I know that's quite the range but of course I'd prefer to be sitting closer to the $500 mark. It doesn't have to be Canon brand. I currently have a Tamron SP AF28-75mm F/2.8 that I couldn't be happier with.

Thank for any help guys [thumbup]! Even if you could point me to a good review site or forum I'd really appreciate it.
