I mailed out a number of mine over the past few years for free. Examples
and some text is at:

It seems to work better than cheap commercial ones and not quite as
well as higher end gratings. I was hoping some of the people I mailed
out to in the past might post some examples of their successes or
failures with these. So far people have been satisfied with them, as
per their emails, but I do not know if anyone has posted pictures.
I plan to make more when I get time.
