Douglas,
Congrats on the new camera purchase. I have rented one after posting the initial thread. I love the improvements that come with this camera. The LCD screen is great and the other improvements have made it worth the upgrade. The 30D was not much of an improvement from the 20D in my opinion.
I do a lot of wedding work---my busy season does not start up until May ---so I am delaying the purchase to wait for the spring sales.
Just an update. I purchased a 40D and love it---but at the same time I upgraded my wedding cameras to 5D and Mark3. In my opinion the 40D is a great camera and with the right glass produces fantastic results.
