From what I can gather, Singh-Ray are at the upper end of the filter market. Their grad ND filters for the Cokin P Series cost about $100 each. Their polarizers, at 77mm are over $200, making the sub-$400 price of the vari-ND seem "reasonable" if it is actually two polarizers.

See the bottom of the review for a note about Singh-Ray.
