I'm new to SLR's but I'm not new to digital camera's and photography. My questions is I've been eyeing a couple of models and I need help to determine which one I should purchase.

I was thinking of either:

Canon rebel XT or XTI

Nikon D40x

Olympus E-410

Which one do any of you think would be the better buy. I plan to focus more on macros and scenery shots. (with some sports shots thrown in). And also would any of these be good for local newspaper print? Any help would be appreciated.....thanks.
