Looks like the Caldigit Thunderbolt station is eating away the sales of Thunderbolt docking station as Belkin is shaving the price on their dock. It can be had for $150 today on Amazon.
I still think the Caldigit is a better buy. I might get my work to pony up for one of these Belkin units so I can play with. Maybe a two-way comparison? Caldigit Thunderbolt station vs Belkin's Thunderbolt Express dock?
