Husband would like a new DSLR for Xmas.

He had an SLR for many years and then we changed to the point and shoot digitals of which we have 3 but we would like to get a dslr.

We have two children playing competitive soccer and the point and shoots cannot keep up.

Looking at either of the following:-

Olympus Evolt E510 10MP Digital SLR Camera with CCD Shift Image Stabilization and 14-42mm f/3.5-5.6 and 40-150mm f/4.0-5.6 Zuiko Lenses

OR

Nikon D40 6.1MP Digital SLR Camera Kit with 18-55mm f/3.5-5.6G ED II AF-S DX Zoom-Nikkor Lens AND Nikon 55-200mm f/4-5.6G ED IF AF-S DX VR Zoom Nikkor Lens

I have tried to research them and am totally confused with all the dslr's out there. I may be comparing apples to bananas for all I know!
Is there something else that would be better for shooting action sports?

Need to keep the price for the package at below $800.

Any help please.......?
