I like olympus.
I have an olympus stylus 800 and besides a few little things here and there I like it. However, you will see good color reproduction with canon, but that is ok.
I just printed over 200 pictures that were taken with the stylus 800 and they came out great.
If you are going to use any of the online printing suppliers go with
www.kodak.com or
www.mpix.com. Those are personally my favorites and very good quality.
