Seat runners failed ?

I can totally relate to all of these posts in this thread and it really makes my blood boil !!!
My drivers seat runner has broken and so the seat slides backwards and forwards into the dashboard !
I have been quoted £166 for ONE seat runner ... and in total which includes labour ... £223.
I dont know about anyone else but I do not have a few hundred pounds set aside in case of failed peugeot components which should last the life of the car !!!
I will not pay the price for peugeot parts .. definately going to a junk yard / used car parts.
It looks as though this issue seems to be very common ... and I thought I had all the bad luck :)

Shame on peugeot for charging us for their faulty mechanisms.
