Quaife and Kaaz LSD

whats the diffrences between the two? i cant afford the Quaife yet, best price i found was 820. Kaaz best price i found is 285. Should i go ahead and get the Kaaz or would it be worth saving for the Quaife? thanks.

I've never heard of Kaaz, but from the price, I would assume its just one of those simple locking differentials (phantom grip). I'd save for the Quaife.
