So I had an old non-functioning atlas 4 color press. Rather than let it go to waste, I threw together some 1 color presses. Here's the fruits of a lazy Saturday's work.
They're pretty sweet, as they're more adjustable than most one colors. You can adjust the off contact, adjust the arm forward and back, move the screen at different angles, etc. Pretty much anything you can do with one of atlas' 1 color presses, but like 1,000$ less.

Pay no mind to the dirty socks...
