The SD980 is out of production and the cost is seeing a typical late-life spike. Check out a newer model, like the Canon ELPH 500 instead. Here's what we had to say about the SD980 in September 2009:
A small step up from the SD940, the Canon SD980 IS is a compact digital camera with a high-definition movie mode capable of shooting video in 720p resolution. It has a 12-megapixel sensor and slightly above-average 5x optical zoom.
