If you've got the cash to throw around, Lancome's Defencils cannot be beat.
But Maybelline and L'Oreal also make really great mascaras. I just got Maybelline's new longwear Unstoppable mascara and I like it--looks natural, lengthens, and stays put, unlike Great Lash (I have never understood why that mascara is so highly recommended--it gives you major raccoon eyes).
Those are my recommendations.
