I don't know where people get $2,000 for the price of a Quaife untit for an R180. $1,200 max and I bet I can get 'em for under $1,000. As far as it being the "best" unit, you'll need to define for what use. It is the best as far as warranty - lifetime and that includes racing and it should never need servicing or rebuilding like a clutch pack (Nismo) unit.
