had the f4 (the one cap is using at the moment actually) and loved it, bought the 2.8 non IS and whilst it is heavier and more expensive it is so perfect, image quality is stunning and the 2.8 is really useful, more so than the IS in the stuff that I do.

As for wide angles, aperture makes little or no difference unless you're into astrophotography of stars and the like where you need a short shutter speed at night to freeze movement (hence wider aperture); most landscapes and general shots will be @ 5.6 or greater so not needed. Check the Tokina 12-24 as well it's the one im getting
