Ford Mondeo Estate - Aftermarket car parts - flowerloverman

Good morning , I have a question regarding aftermarket car parts , OK , I am replacing my timing chain kit at some point in the coming weeks , I've had a look around various small and large motor factors in my local area and 2 brands keep getting offered , Fai auto parts and Bga automotive parts , both of which are classed as oe (original equipment), has anyone used these brands of parts and if so are they any good , I have enquired with Ford and although they offer a kit as such , they will only sell the relevant parts separately , and so this becomes very expensive , a friend of mine has said that Ford have suppliers that make the parts that are fitted to their cars when being built and most likely use some of the 2 brands listed somewhere along the line , any advice appreciated , thanks in advance
