This model is quite old and difficult to find. Check out a newer model, like the SD1300. Here's what we had to say about the SD750 when it was released in March 2007:
Slim and sophisticated, the Canon SD750 is an ultracompact Elph with a massive 3-inch LCD. Similar to the SD1000, the SD750 has a larger LCD and a slightly thicker body, featuring a metallic finish and a circular accent around the lens. Meanwhile, inside the camera, Canon's DIGIC III processor is at work with Face Detection and Noise Reduction, ensuring great shots under almost any conditions. Speedy operation, improved image quality, and long battery life make this sleek camera ideal for the style-conscious as well as the photo perfectionists.
