Official PS2 component cables were trash. Official PS3 component cables on the other hand are rare and expensive. Same with Original Xbox too.
I use an xploder HDTV player cable on my PS2, it works fine on the PS3 & it's lasted a long time now. I don't recall ever seeing an official PS2 component cable in the UK.
The original Xbox component is more complex, they only sold them in the US. I got some from a bankrupt game developer.
