Ah yeah, go with the Canon. Thats sort of a mix between the elph's and the SLR's. kind of somewhere inbetween. its not a true SLR, so it will do your video for you, and the lens on that is much nicer than a compact camera's lens, so your pictures are going to look alot better.
If you are looking for the price of a point and shoot, but want a littler better quality in your image, and dont care that its a little bigger, (no changeable lenses though) i would get one of those.
Although, if you save up you can pick up a Rebel
