I appreciate everyone's input in this topic, and I have been tried the Tamron 18-200 at my local Wolf store and I am sold on the 18-200 range. It will allow me to stick with one lens, helping ensure I don't miss a shot because I have to switch lenses, and gives me the current range of the 18-55 kit lens, but allows me to take it out to 200 for those close in shots.

My new decision facing me is determining which lens to get. I know the Sigma 18-200 OS is out there but I don’t know if I really need it, or it's more of a wish list item since this is only a mild hobby of mine. I have checked reviews, and they say the Sigma has slightly better quality of images, but the Tamron is quieter and faster at AF. Does anyone have any experience with these lenses? Also, in the store at the far end of 200, the AF did work on the Rebel, so I am still a little lost on the possible issues of not focusing at f/6.3.

Does anyone have experience with Sigma's OS lenses? The guy at Wolf informed me that Tamron makes lenses for Canon, so they have some of that information, which make them work better sometimes, but I don’t think they have or are coming out with their own IS version of the 18-200 like Sigma or even Nikon has with their 18-200 VR (obviously not an option here)

Any further help or information would still be greatly appreciated.
