'Keos adapter'

[gill]

Hi: i searched adapters forum, googled ebay to locate any information on Keos adapter by Mr. Rolfo's product. If it has already been posted and due to over sight, I regret. At present i have 400D which is doing fine with PK adapter. In the near future like my other colleagues intend to add full frame eos camera and intend to use my Pentax K lenses without shaving the aperture lug of lens to use on film camera. I read somewhere one can replace the aperture lug with Keos adapter and vice versa. Any experience & information will be grately appreciated.
