I would make sure its a wooden fingerboard, I own a moon board and a beastmaker/varian/ned board. I prefer the beastmaker. You dont need to go to any expense though you can always just hang from a strip of wood ala Dave Macleod.
it weighs about 1kg and its been designed to fit nicely above a door with a bit of elbow room too
i spent a while designing mine and then redesigning it because all i had was good crimp strength and one trick ponys don't win races.
So i hope i've sold a few more so i can tell everyone you can't have one because were still rebuilding our machine and it'll be atleast a month before things get going again.
