I agree with Rinnie; if you are getting these cameras, I hope the price is very low or they are being given to you.
I would opt for theS3000 as I like the 6X optical zoom.
If I had $100, there are many other cameras I would get before either of these.
One current bargain to consider is the Canon A590, which is selling at Sears for $119.
If you want more helpful advice, you should answer Rinnie's questions - What are you taking pictures of in what kind of conditions?
