What is the BEST MAC, Chanel, Dior, ect foundation to use?

I love my MAC foundation, plus it's cheaper than say, Chanel! Go to the MAC counter and ask the girl if she can help you find your perfect foundation. Make sure to let her know your skin type: dry, oily, normal, etc. She should ask you this, anyway. They helped me find a great foundation. It took 10 minutes and $26.
