I bought a
Acase Kindle Touch Leather Case from Amazon ($11.45 w/ free Prime shipping) and the fit is perfect especially when I put in the T1 upside down! Also, since the flap opening is now to the left, the flipped magnetic closure secures my left hand well when I read one-handed. The stylus stays in quite snugly as well.
In fact, the fit wasn't bad when the T1 was installed as intended. The bottom leather holders covered the prev & menu buttons slightly, but they stayed where the buttons bevel down and didn't push the buttons down on their own. Yet, with the T1 upside down, it's almost like the case was made for T1.
Overall, great price for a good-looking and well-functioning case. I'm totally satisfied.
ps. I'm taking back the recommendation IF you have a white T1. I took out my T1 today and found that the interior lining's grey color had transferred to the T1 (where the back curves in, about half an inch inside each edge). Lysol wipe took most of the bad spots out, but not all. I've found that the white T1's back tends to get dirty very quickly, but this color transfer incident has been the worst of all. Stay away if your T1 is white.
