Firmtek just came out with a much cheaper USB3 enclosure. They're selling them for $40 at "introductory" price.
http://firmtek.stores.yahoo.net/dlite1.htmlI just tested one and it's fast. Someone else tested them here:

No connection to the company, other than owning several of their wee boxes now.
