Does anyone know where I can get hold of the polygonal mirror + stepper motor assemblies that they use in laser scanners at checkouts? The "legit" parts come with boards attached and cost a fortune; I'm just looking for something cheap and second hand.
A user here (sethc) had a bunch of them under his desk which would've been perfect, but that thread is from 2009 and it doesn't look like he stuck around.
Anyone else got a source on them?
