I've been considering buying the S2. I have my canon rebel but also a Canon A95. I have the A95 if I want to take pictures somewhere and not risk having my Rebel stolen. The A95 was $500 when I bought it. I was thinking of selling it as using that money towards a new camera (S2) I don't know how much I could sell it for. I think I saw the S2 in stores for $400 or so...so even if I could get $100-200 for the A95 (no idea what it's worht right now) I HAVE the money for it, I just feel like I'm spending too much on something I don't need. I HAVE a great camera already...

Would you say it's worth it? Is the S3 a whole lot better?
