I have to say I own a lot of Mac brushes and now have quite a few Sigma brushes and I love them just the same! SIGMA BRUSHES :: Dupe List for Mac Brushes. I have a bunch of both, and it is true, they ARE great dupes.
Dupes for Mac eye shadow colors that you can find on Urban Decay's Naked Palette. Urban Decay does not test on animals, while Mac, unfortunately, does (after it was bought by Estee Lauder, a real pity)
