Details on the Canon focusing screens for 1D III

[Gautam Biswas]

Where can I find the detail specifications tof the many alternative focusing screens for Canon 1D III. I am looking for one which will be useful in assisting in precision focusing- split image or microprism as in old days, in addition to retaining autofocus.
