I'm more inclined to go with the S45 due to the fact that it's a newer model. I got my S45 from Dell but I haven't opened it yet. A friend of mine offered to sell me his old S30. It seems to be in very good condition. However, it seems like a good idea for me to save myself $150 and go with the S30 since it's going to be my first digital camera anyways.
Anybody else have any opinions?
