I got the SONY cable.. I don't know the difference between cables.. but it seems pretty awesome ? It says recommended for PS3 (Obviously- Sony>PS3, No question) thanks for the help and facts about HDMIs it's deffinatly better to play in HD!
I don't know about Canada but the cable you mentioned is about 40€ in France - generic cables are around 5€, yet are the very same and work equally well.
I bought a $30 HDMI for my PS3 after getting a new TV. Looks amazing.
