I found a canon g5 for 50$. Given that the camera is several years old, do you think this is a good deal or will it likely break down soon? From what I am seeing all this megapixel jazz doesn't mean much, I tried a cheapie out that saved in huge resolution but the picture still wasn't sharp. I am thinking this camera, even though old, is probably still better than the 100$ jobs at walmart but then again I only have experience with one of those cameras. Thoughts?
