Decided to take the plunge and finally buy an official PS3 controller. Sadly they are quite expensive and upon searching eBay I have found a load of sellers selling "unboxed" and "bundled" PS3 controllers (Opened a brand new console and taken the controller out) which is kinda believable.
But this leaves the opportunity for fraudsters to take the plunge. I've seen them quite cheap at £20 but I wanted to be 100%. Say I receive a controller, how can I tell if it's genuine?
