I’d sell or trade in the EOS 3. (Unless you have a specific reason to continue with film – ie infrared, slide, or hand printing monochrome work). Damien tempted me into going digital, and since that time (May?) I have ONLY used my film bodies (2 35mm Canons, 3 35mm Nikons and a 6×9 Fuji) for jobs where I have been working for another photographer who insisted on film.
