Photo Gallery Plugin?

What's a good photo gallery plug in that will work with WP 3.0 as a network of sites? I looked into NextGen Gallery and it has lots of features but it also has a lot of extra panels in its admin interface, advertising and such. I want to be able to offer my users a simple to use photo gallery plug in and I'll be creating a how-to video so a medium learning curve is okay. What's everyone else using?

Thanks.
