I would drop the Casio from the list.
It does not have image stabilization.
It is difficult to hold a small, light weight camera, steady.
So you need image stabilization.
The Sony has HD video, the Canon does not.
Otherwise they are pretty much alike.
I want to spend around $100 - $150. Here are the ones I've been looking at so far:
Canon Powershot SD1300 / Price: $109
Sony Cyber-Shot DSC-W350 / Price: $140
Casio Exlim / Price: $80
I'm simply just looking for a camera to take some good shots for general travel and photos with friends.
I'm sort of leaning towards the Cybershot due to its good reviews and small size. Anyone have any other suggestions? Or would the Cybershot likely be my best bet? Thanks in advance.
