The Pro is 8MP and the rebel is 6MP.
She I think she'd like the 1DsII, but can't
justify it for what she's doing at this point.


Honestly, the Pro can take really great pics with some practice. A lot rides on
how you print them.
My new Nikon 8800 is 8 MP. I've already taken some greats shots...but it's easy
enough to get it wrong, especially with the focusing. I'm glad the 20D has true
manual focus.
Your wife should take another crack at it and take her time. An Epson R300M
will deliver excellent 8X10s as will the 800. They are terrible for regular
text printing though.
