I also have the Y550 and purchased the Zalman ZM-NC1000. The laptop does hang off the sides a little but I'm very happy with it. I have had it for about 4 months and it still works great. New Egg is selling them for 42.99 but you might want to shop around. The cooling pad is USB powered and does also come with an additional USB port.
