Those kits are pretty much generic chinese-made kits (cooling pro, autobahn888, same same), though you do get a full 13 piece set.
Samco are the best silicon hoses (that I'm aware of), but quite expensive, $300-350 imported only gets you 4-5 heater hoses. http://www.samcosport.com/row/car_kits.asp?make=Nissan
