I've been building my own scanner stands for years. 1pc -1/2 x 2 Alum flat bar - 4inches long. 1pc. - 1/8 x 2 Alum. flat bar 6 inches long. drill and screw the thin flat bar to the front of the bigger block, and give it a little bend backwards for pitch. Not high tech, but they work. Maybe I should build some for sale.
EDIT - I posted some pics in my album.
