Best Mascaras on the Market from Cheap to Steep

Named the best mascara several years in a row in InStyle magazine's Best Beauty Buys issue, this Lancome Definicils not only lengthens lashes, but won't clump. I use it every day, having tried many mascaras. Keep in mind: Mascara is one beauty product you don't need to spend money on (see other best buys below). However, I happily spend the $20 or so this product costs.
