Hey Chris,
For a bit cheaper you can get the MEZA mounts on Amazon. Very similar to Monstertech and the only caveat of canting the Winwing Throttle due to the center plugged USB. Here's a photo of my Orion with Meza mounts. Overall happy, wish the rubber pads were "stickier" on my smooth desk but I can fix that. $189.99 on Amazon for both.
