Weird, I just bought a Seagate Thunderbolt dock from the Apple store for $430, and it came with a 3TB HDD, enclosure, and TB cable...![]()
The goflex seems the best TB option at the moment as you can easily swap the HDD for any other SATA drive. There seem to be plenty of goflex enclosures without drives on eBay (in the UK at least) I've bought a few and fitted my own drives to them.
