Well here's my thoughts on the subject =)
The Canon EOS 350D (Digital Rebel XT) should not even be compared to the Nikon D50 - if anything, compare it to the Nikon D70s.
I have tested the leading low-mid price D-SLR cameras on the market (Canon EOS 300D, 350D, Nikon D50, D70s and Konica Minolta Dynax 5D) and my personal opinion is that the EOS 350D is the winner. The Konica Minolta 5D just wasn't anything I liked at all, so I won't even talk more about that one - and due to the fact that Konica Minolta stopped producing cameras earlier this year.
This is in fact a fight between Nikon and Canon.
What I really hate about the D50 is that it's the only one of the mentioned cameras that uses a SD card, instead of the CF card that is standard in most other cameras. I've read that some people here comment on the Nikon cameras having more colors and "punch" in their raw photos - well that might be true, but to me this is a bad thing. I myself have turned off all extra contrast, saturation etc on my camera (EOS 350D), just because you will lose some of the image quality with those features turned on. I want to be able to edit my photos myself, and that way get the best possible quality.
One thing that I like more about the Nikon cameras is their size, gives them more stability and are easier to hold (for me at least). However, Canon are winning even this battle, why? Because they have a extra battery grip you can attach. This battery grip gives you the option to have 2 batteries (up to 4000 photos on one charge is the maximum I've had) but best of all, you have an aditional "trigger" so that you can hold your camera vertical without twisting your arms.
There is however one aspect where I feel that Nikon is better - it's the kit-lens you get with the camera. I don't like Canons kit-lens that I have now (18-55 EF-S), but the Nikon kit-lens is quite good. But then again, most lenses I own are from Tamron or Sigma, so for me that doesn't make such a big difference.
As for printing, I've gotten best reuslts from the Canon cameras. Both the 300D and the 350D have produced really high quality images at sizes up to 28x40 inches (70x100 cm) - I haven't tried any larger then that. The Nikon D70s could not maintain the quality at this large scale - but on smaller scale, 8x12 inches (20x30 cm), they were tied.
So all in all - I would go for the 350D, buy the extra battery grip and a Sigma/Tamron lens.
