Thanks for the case info, merlin1!
Meanwhile, I found a low price case solution. I bought a small CaseLOGIC zippered neoprene case with mesh inside pocket for accessories such as storage cards and a zippered outside pocket that is great for storing my Apple USB Ethernet Adapter along with the short AC power cord that plugs into the power brick.
Measures about 5-1/2" wide x 8" long.
Model UMC-5 Black, Universal MP3, $22.99 on CaseLOGIC website...I paid $19.99 at local store.
