Hi all! When I first got my XSI I bought one of the best tripods available at Circuit City to go with it. It served its purpose at the time. Since then however, I have upgraded my kit, purchasing an amazing 24-70mm canon lens. Now I have a problem though. That tripod that I had thought to be a good tripod, can no longer sustain my camera equipment. My question is, what tripod setup do you guys recommend I buy...in the $300-400 price range that can sustain a lot of weight. I would appreciate any advice you guys can give me! Jose S.
