i think its worth the money, the only reason people go for the more expensive ones is because of the 19mm inlets, what ive got for mine is a small length of 15mm I.D. hose to go to the catch then a 20mm-16mm reducer then the rest is 19mm oil hose with a t-piece chucked in there, all tightened up with some jubilee clips. thats the plan anyway. I did ask a garage about using 15mm inlets and a small amount of hose and they said there would be no problem as generally the original hoses are so gunked up with crap theyre pratically 12mm if not worse.
