The Canon SD series of point and shoot cameras are very popular and capable even though they have been discontinued and replaced by the "ELPH HS" series. These cameras are light and portable so you can take them anywhere and yet they are still powerful enough and capable enough to take snapshots in most any situation. Parts are still available for most SD series cameras, and they aren't usually expensive which makes repairing these cameras very worthwhile.
