I also have the 17-70mm Sigma lens. Upgraded from the 18-55mm kit lens and I love the range it offers. Kit lens was just too short on the telephoto end. This one is just about right. Yes, there are few occasions that I would like to have more reach, but I also keep the 50-200mm in the bag. So I would sell the 21mm, get Sigma and keep the 50-200mm lens. But if you do not want to carry two lenses, then go with 18-250mm. I guess it all depends on what subjects are you photographing. For my casual family snapshots, few landscape and portrait shots, Sigma is more than enough.
