Rolf,
I don't know about the magazines, but I saw a review online comparing the MFJ-916B to a Diamond MX-72:
http://www.w4gso.org/news/comparing-duplexers-mfj-vs-diamond/
The MFJ unit outperformed the Diamond unit.
I have been using the MFJ units for years. They are made in Taiwan, and are priced at about half the price of the equivalent Diamond or Comet units. They are rugged, and work well.
73!

MFJ sells a duplexer (aka Diplexer). The model number is MFJ-916B. There are other manufacturers also such as Comet and Diamond, etc.
There was an article not long ago in the Amsat Journal, (or was it QST?), comparing different models.
