Timing Guide Rail - Metal?

[msega]

Has anyone tried the metal timing guide rails that Meyle has come out with? The timing chain job on my 420SEL has to be done soon, and the metal one costs almost as much as the plastic ones at the local dealership.

I'm trying to avoid the plastic Febi part because I've noticed the quality on Febi parts start to decline.

Also, do the pins have to be replaced?
