About a month ago I spent a ridiculous amount of time online researching cases like these without a hub (including Amazon) with little success. (I didn't want the jewel case). I finally found some from a place in the UK called Riviera Publishing
(scroll all the way to the bottom for the Multistorage Case 14mm Spine). They were super nice and I got 50 of them for about $50 so I was pretty happy. I have the SU ones and these are just about exactly the same thing. I'm glad to know that Amazon has these because they're a little cheaper. (The ones from Riviera Publishing don't have that little clip on the inside cover that would hold paper literature on a real DVD).
