I came from using a Nikon F90X. I was ready toget the 300D since it was the best deal in early 2004. Then the D70 came out. So I got the D70. There are various pros and cons for both that can be endlessly debated, but it all boils down to intended use and budget. Product-wise, you can take great pics from using any of the two. The D70 is better for action shots, but Canon has the best local deals and support. Needless to say, I love my D70. It seems easier to get good quality 2nd-hand fast telezoom lenses for Nikon (80-200 2.8/AF-D), but fast primes seem to be affordable for both (50mm 1.8s). The D70 feels very solid, and lightweight at the same time. Sinve April last year, I've taken almost 12000 shots with it and its working fine. Go Digital! Now's the time! A new Rebel's out and a D70 or D100 successor is supposedly in the wings.
