Actually the only way to tell if it is going to be a worthwhile fix, is to first get the solder off of there to see what the damage is, fixing the 2D is not a difficult thing, but you are going to have to find someone to braze the metal, as looking at what they did to fix it, I can only imagine they stressed and then broke the metal, as it is a functioning camera, I would not be so quick to say you need another one, I have had to fix a couple of brackets over the years, and really it is not that big of a deal, but your first step is going to be getting the "Fix" off to see what is underneath it. Actually I might even have a couple of these pieces around here...
