If you do get a 18-200, forget the Sigma and go with the Canon version. You'll find that with the high pixel density of the T1i, some lenses will be out resolved by the sensor, and you'll notice a particular lens' shortcomings are greatly magnified compared to say an 8MP DSLR. Get the sharpest lenses you can afford.

I've had so many customers complain after buying a 5D mkII that the camera is not producing sharp photos, because the lenses they used on a 5D were tack sharp, but the images look soft on a 5D mkII. For example, an older 28-135mm EF lens is great on a 5D, but on a 5D mkII, it's not very good at all, as the 5d mkII has a higher resolving power than what the 28-135 lens can produce.
