Recommendations for a M/42 Adapter for Canon 1DS

[flintlock1]

Hi All,
Can anyone with a Canon 1D or specifically a 1DS recommend me a good reliable M/42 adapter with focus confirm chip that works 100% please.

When i had a Canon 350D, i bought from a no-name seller on E-Bay a Fairly cheap, but usable M/42 Focus confirm adapter. It worked fine with the 350D, but when i sold the camera and moved to the 1DS, the same adapter would not work.
Other Forums and user's have mentioned something to do with it not activating the small micro switch in the 1D / 1DS mount, at about the 10 oclock position on the camera?

Any help gratefully received, as i need to start using my M/42 collection of lenses.

Buy EMF chip, so you can micro adjust the confirmation. You also get some basic exif data with this programmable chip.
You need to activate that switch on 1d. Use piece of paper of what ever so that the switch stays up.
