Looking for a decent karambit w/ sheath

I don't think SRM/Enlan produce karambits so i'm looking for one with the similar quality and price levels. Any pointers?

They don't produce karambits, the most similar could be the navy 501 (it isn't karambit exactly) --> http://www.exduct.com/Chinese-Folding-Knives/Navy-Knives/K501-Navy-Folding-Knife.html
