I have the A570IS, and have enjoyed it. I've never had any difficulty with the build quality (my poor camera is often thrown into my purse at the last moment, is not kept in a case. I did drop it once, on carpeting, and it still works!). The image quality is wonderful, and it has some manual controls so your not stuck with only using auto mode. I am, however looking to upgrade because I need more zoom then 4x, and I do find the camera a bit slow from shot to shot. Other than the speed and wanting more zoom, I think the A570 is an excellent camera.
