Thunderbolt to USB adapters (update)

Hi all,

I'm starting to look around for a Thunderbolt to USB adapter specifically for and dedicated to my Virus.

Kanex, Sonnet and Startech all seem to have models which do USB3 and eSATA.

Since I'm going for a Sonnet PCIe chassis, I'm leaning towards their unit.

Does anyone have positive experience with any of these adapters?

Thanks!

For what it's worth, I have the Sonnet Thunderbolt to USB and eSATA working, using 5.1.1.0.
