Black Opal Cosmetics True Color Liquid Foundation [D]

I've been using Black Opal foundation for years. I love the application of it and how good it matches my skin tone. I use a pressed powder on top of it and get all-day wear. I want to try other foundations but Black Opal is so good I'm afraid to be dissappointed by anything else and risk wasting my money. So I'll stick with what I know works for me.
