This may however require a bit more pixels than the 6Mpix of the 10D.

The cheapest way of getting a grid would probably be either to buy a
shade for your camera's LCD, and build a fine wire grid into it. Or
with a fine mapping pen and appropriate ink draw fine lines on a
plastic LCD screen protector.

Small perspective and tilting adjustments can these days with good
software be done with very little impact on the detail resolution
(i.e. hard to notice any loss), and being small corrections, there is
very little loss of pixels in the bits of edge which get cropped off.

The losses of software corrections have quite understandably been
exaggerated by the people in camera shops who hope to persuade you to
buy a lens which won't need to be corrected, plus all those people who
bought one :-)

Yes, the Nikon D5000 does as well.

I believe I mentioned "other models do" actualy maybe all of them, I
just looked at the 1000d, it has grid. Forget the auto focus points as
they are momentary , dpreview will show you displays of canon dslrs,
or google it works.
