What's wrong with a Canon 7D + 70-200mm f2.8 L (original, not II)? You should be able to get both for around half of your stated $5,000 limit.

(On a personal note: I don't have any trouble shooting volleyball in single shot mode, and I shoot RAW so I can adjust WB in post. You could do the same on your XTi if you want to save yourself some money.)
I want to buy a new camera and possibly lens. I currently have a Canon Rebel Xti and a Tamron 70-200 F/2.8 lens, but I want better. I want a faster fps camera to catch better volleyball photos and better hockey photos. Obviously need something with a good white balance for those hockey pics. Not super concerned with price, but I don't want to spend $5,000 either. Anyone have some good suggestions?
