On a crop sensor a wide angle lens will seem to have a smaller field of view. Worth it or not depends on how wide you want. For pricing specifics and alternative options u might get more response from the Canon forum.
The 35mm will have a slight one stop advantage with having a larger aperture
so getting lens with f/2.8 will be a better choice. Mmm.. very new with cameras. which lens wld u advise me to get? cos this camera i share with my hubby. this lens is a xmas gift for him. cos he plays with photography more than i do. is 28mm enuf?
