looking for a greddy type s

[bob123131]

A picture of the diaphrams will show you nothing. The ebay ones are same design and do sound the same however the diaphrams are not protected with ? i forget the name but it is stop oils from eating away the rubber giving them a max of 6 months life. You can buy a 20 dollar ebay one and a 8p replacement diaphram though and you will have better than a used greddy type s for only 100.
