Hi I am looking to get one of the adaptors listed in the title to hook up my PS3 to my iMac. What do you recommend and why? Are there certain things which stand out from one over another? At the end of the day, do they all accomplish the same job with similar quality? In the UK I seem to be having trouble locating somewhere to purchase any one of these. The Dr. Bott is the only one currently I seem to easily be able to buy: http://store.apple.com/uk/product/H0570B/A?mco=MTcxODkxOTc Hope you can help, thanks.
