I am using the Vetra844u Multiplexer. The version I have is a beta unit and DOES NOT WORK with the Nostromo N50 or N52. I do not know if the issues I had were ever resolved.

After playing around I found the best solution was the Ideazon Fang . This works great with the multiplexer. The out of the box macro/layout software was complete trash and I almost gave up on the product until finding the current version of it online. With the updated management software this worked great. I have been tempted to try out the Saitek PZ31A but have not felt like spending the money on one.
