I used to have a logitech wireless controller but I got rid of it when I got my slim PS2...it annoyed me that the reciever was too big for the slim console. Did they shrink it in newer versions? Also what is the difference between these 3? http://www.logitech.com/index.cfm/products/productlist/US/EN,crid=2276,categoryid=285 Just vibration? It looks as if the reciever for the no vibration black one is smaller. Any help would be appreciated. Thanks.
