i guess its a good a spot as any.
welcome to the forum by the way!
I believe several people own the 350D on the forum, and plenty more own the 300D. The only main difference i could tell was that the body has been slightly modified, the sensor has been replaced with the 20D's CMOS sensor, it uses DIGICII imaging, and its a smaller camera than its predecessor.
All in all, i was thinking of getting this camera, but i settled for a 10D.
What is your budget? What are you wanting to do with the camera? Those types of specifics will help us determine what advice to give.
hope that helps!
