I have purchased a T3 second hand and am having having one very significant problem that has cost me several rolls of film. As I am midway through a roll, all of a suddent the camera will blink 00 instead of the frame it was actually on, and locks into place. It won't advance forward and I cannot manually rewind it either. I have been forced to open the back and pull the film out. Any thoughts and suggestions here would help. I'd rather not send it back to Contact as their min. charge is $150. I live in Miami, so any local repair shops or ideas would be appriciated. P.S. I also occassionally have had a problem with the takeup spool which I understand is a common problem.
