Several threads discuss Ergotron's quad LCD monitor stands. I have had these priced out and have squeezed to get the lowest price possible. Unfortunately, I find them to expensive even to buy in bulk. I'm looking to replace the current setups for each of my traders with Quad stands. It is more efficient to look at monitors in that configuration rather looking across their desk at monitors set side by side. These stands cost almost as much as a new 19" LCD. Does anyone know where these can be had for less than $200 a piece? I don't mind buying them used as long as they are consistent.
