I have the previous model (Delta series) of the BookArmor case for the PRS-950. It is similar to the current one except for the way the reader is attached to the case. In terms of durability and protection for your unit -- it is just GREAT and worth every cent to protect the sensitive screen. Some people may find that it is, unfortunately, a little heavy -- but is worth the tradeoff to protect your big $$$ investment.
