I've had the Belkin dock and it was freaking terrible. Support was also awful, I ended up giving up on the thing after months of arguing with them (and it).
BillWeissWas your dock the original Belkin Thunderbolt Dock or the currently available Thunderbolt 2 Dock. Also what issues did you have with your dock? Very interested to hear more about your experience....
GDLutzGood call, it was the original, not the 2. I had two issues: it made my Mac crashy, and their support was super super bad. The former could be fixed (new technology, after all), but I'm not convinced the second has been.
