I ordered this one:
Amazon.com: Poetic(TM) StandBook Stand Leather Case with Angle Adjustable for Asus Eee Pad Prime TF201 Black: Electronics
Looks to be very similar to the Blurex and Vertek case except for the color of brown vs the Blurex/Vertek blue. Still waiting for it, but a user on Amazon took pictures of the case with shipping. It has a charge port so you can use with the case on. I know some don't. Personally I would have rather had the blue lining but I would much rather have a case period. The Blurex and Vertek have been out of stock for a while and I stumbled on this while looking for those. It's also $20.
EDIT: Poetic lining is actually a light grey and the Amazon picture looks light brown.
