Good choice. I have the S50. A bit older, but it has a larger LCD viewscreen than yours, and it flips up and down, around, to the side.....all that good stuff. You'll love the camera.
Now go buy this:
Or the 230.....I have one, and it'* the greatest. Well worth the money (I got it in a drawing at work....an even better price). You can find it cheaper than this. I've seen them quite often in the 125 range. Memory stick just plugs in. It'll print a contact sheet of all pics on your card, and prints 3 different sizes. I cut my own sheets now from normal sized photo paper, it'* much cheaper.
