As mentioned in an earlier thread,https://photography-on-the.net/forum/showthread.php?t=78223, I have an onboard flash on my 20D that worked intermittantly at first, then died for good. I have not been able to find a consumer-level fix for my problem and so am faced with the prospect of sending the camera back to Canon under warranty (which expires in June) I have almost no reason to use the onboard flash as I have other options that give far better results (see sig). I do not want to give up my camera for any significant length of time (more than a week). On the other hand, it is a new(ish) camera and everything should work. In my situation, how many of you would suck it up and send the camera back (for how many days?) and how many of you would keep on using the camera as if it never had a built-in flash?
