I just received the
TuffLuv case for the Sony 650 that was mentionee by
SCION.
The case was $20 total after shipping and handling from England to Canada!
The case fits perfectly snug. There is a small one-eighth inch gap at the bottom that could be filled with foam if needed. Without the foam spacer, the kobo can be pushed right to the bottom and the home button is covered if you do that. It's not really necessary though. This case is great, although a little heavier than I expected.
Being cushioned, it's really comfortable to hold onto and protects the reader nicely. It's not too floppy so I find I can hold the eReader many different ways, including folding the front cover right around to the back.
