North Creek Kits: good good to be true

A friend of mine who has been in the industry for a long time, and he suggested a company named North Creek who sells high end kits with really good drivers. It seems too good to be true that you can really good crossover and drives for one third of a price of good speaker. Does anyone here have experience with this company?
