IMO you're best going with either the Canon or the Nikon. Don't forget that you're not only investing in a camera, but a system of cameras, lenses and accessories. Canon annd Nikon have the widest range of equipment and accesories. You could compare it to buying a Honda or a Hyundai - they're both going to do the same thing, but one of them has more support when you want to upgrade.

Also, I have no way of telling you which one is or isn't a bargain because you didn't post links or prices. What brand are the lenses that come with the Olympus?
