CM Becker makes forward seal beer faucets that have a built in creamer function. They say they're made in Germany and assembled in the USA. I've just started seeing these in ads in Zymurgy and other beer mags.

Appreciate the info. They look like great faucets. However there doesn't appear to be a good control option. For me...that's key #1 at this point. Also...I will cut Williams a bit of slack but as yet...still no response.
