I've been searching for a nice case the last few days also and found the Sony case with light for $37.99 and free shipping at
B&H Photo.
I was also very tempted to order a case from
KreatedByKim, I've read that you can give them the dimensions of your device and what type of pattern you'd like and they'll make it the way you want it. Also the
M-Edges here looked pretty good.
I might still get one of the smaller ones for when I take the reader out during the day when I won't need the bulkier light. But there are times at home I need the extra light, and from what I've read about the Sony case, I think it'll be perfect for my home needs.
I do know that Amazon has the Sony cases without the light also if that's your preference.
