Where can I find a replacement? Will the one's on e-bay work? Does anyone know where I can find a parts list? Also, for those of you w/ a Canon 40D....what is interchangable with the 20D? I have the shutter release cable and the hotshoe cable for the 20D, will it work on the 40D? Also, if I'm not mistaken, don't they use the same battery? I'm upgrading and would like to keep as much as possible. thanks marie **Nevermind this question....I found my answers on the Canon estore website! Pretty amazing when you actually stop and look something up!
