Wendel's VESA Monitor mount: Where Can I buy/How Much?

     I've been looking for a good VESA mount for LCD panel monitors. I'm trying to find one that lets you easily move the monitors to be facing in different directions. I've seen some gas arm lift types online however purchasing one in the US seems to be a little tricky. And most of the prices I've seen are ridiculous. I don't want to spend more on the stand than on the monitor itself. I was wondering if anyone could shed some light on the best place to find one of these? 

His monitor arms are by SpaceCo (which he mentions in his office tour video). They can be found @: http://spaceco.com/

It's very expensive to buy them from SpacecCo directly, try Ebay.
