Hey, Oberon Design has finally got leather covers out there for the PRS 700 & 505, and they *are* gorgeous! There are no pictures of the interior up yet (I got an email that said they should be up sometime this weekend) but they have all the various patterns & colors up.
Much pricier than the M-edge ($72), but oh-so-pretty! They use the same corner securing idea as the M-edge executive.
I feel the call of a Red Leather cover...
