I won't bore you with the list, but I carry a large number of Lee GND's. The quality is superb, and they're well worth the money. A set of three standard GND's in the U.K. is around £110.
Prior to switching to Lee, I used Hitech for my LF work, and I've kept hold of them to use with my DSLR. They're great value for money, but the range isn't as extensive as Lee, and they're a little thinner and less robust. HTH.
