I would stay away from this lens. If you haven't noticed, the 18-55mm that comes stock on entry line digital Rebels is the equivalent to the 28-90mm. The only difference is that one is made for digital crop cameras, and one is for full-frame/film cameras. An 18-55mm yields the range of 28.8-88mm, similar to the 28-90mm that you're looking at.
This 28-90mm won't be wide, or even long at the focal length, making this an odd lens for a crop camera. 44.8-144mm is the effective focal length on a 1.6 crop factor camera. You might as well pick up the 18-55mm, since you can find them for around the same price, or cheaper.
