I have an Evoluent Mouse that lets me put my hand in a neutral position which is much more comfortable.
I also have a SpaceNavigator, but it does not let me put my hand in a neutral position. I made this stand to fix that. I had to recalibrate after putting it on the stand, but it works great.
I also added some memory foam from McMaster Carr to support my wrist.
