NOTLguy,
I bought a case for my PRS 350 from ebay. The seller also offers one for the PRS 650. There were no import charges, it was shipped very quickly (within about 3-4 days) & the normal shipping charge was about $3.99. It's not "real" leather, but the case is nice. It offers access to all ports, switch, & stylus.

Noreve just started offering a case for the 650, but it is expensive, expensive shipping, but no import charges. Noreve cases are extremely nice.
