R26R clutch and SMF

Hi,

Just want to check I am looking at the right parts before I order anything and then they dont fit!!!

SMF - The TTV one from RS Tuning for £359
The R26R clutch and slave from eurocar parts for £195.99 here: http://www.eurocarparts.com/ecp/c/R...59ad3a88e1665e9db07eddce4ef44ef874ac3b&000069

But they also list a more expensive one below: http://www.eurocarparts.com/ecp/c/R...779230e074ddc2a811efd8cb3f8faf2508b475&000069

then try get a local place to fit, or just drive the 2 hrs and get mark black to do it for £775
But I can not really see a difference here,

Are the LUK cluthes any good? or just get a OEM R26R clutch?

I know this topic has been done to death and I have searched but not really found any recent links to actual parts,
