A Samsung SCD80 camcorder to a new zr850? I currently have an SCD80 ( http://www.amazon.com/Samsung-Compact-Digital-Camcorder-Display/dp/B000069F70 ) and I'm wondering if the quality of the video would be worth going to a new zr850? ( http://www.amazon.com/Canon-ZR850-MiniDV-Camcorder-Optical/dp/B000M4JDQQ ) I've had the Samsung for a good 4-5 years and the zr850 would only run me about $150 new. Worth it? My usual tasks are video taping random special events outdoors and in with the family, editing with imovie, making DVDs, ect.
