Hi I've been looking at a solution to having a 'cheap' overhead with my main display. This is cheap in comparison to buying a tangible overhead.

Basically I'm look at setting up 2 monitors one on top of the other. and the one on top tilted.

This is the closest thing i have found that can be desk mounted but will cost AU$ 420 with the right amount of arms.

Does any1 know of anything cheaper?
