I have the MEdge Leisure case for my Sony and like it fine. It's very useful for travel. It has a padded frame and a clear plastic cover and zips shut. This allows you to see the screen while it is protected. In fact, you can place the reader into teh paded frame screen first which adds good protection when it's in a carry on bag or purse. Although not completely waterproof it is water resistant and thus a good choice for the beach or on a boat.
I got one back in February and like it fine. The zipper eventually broke and I sent MEdge an eMail asking how much it would cost to fix and, without my asking, they sent me a replacement cover at no charge. That's impressive.
Anyway, they do accept international orders and you can look at the case here
