Buying a timing chain

[rkpatt]

I was seaching the web to buy timing chain for an OM602 engine and saw listings for the usual Iwis chain and one from Beck Arnley . The Beck Arnley chain 024-1380 timing chain was priced much lower than the Iwis timing chain . I wonder if the there is a catalog mistake or it is one that fits and and is of decent quality. I have used Beck Arnley parts on various cars for years and found them to be ok but never a timing chain . Anyone familiar with this ?
