I bought this one http://www.mobilefun.fr/36644-housse...---pourpre.htm
for its quite cheap price and good looking, but I must say I'm facing the same issues as mentionned regarding the smart on/off switching
Many times flipping it off doesn't put the Kindle in standby, and moreover, I can't even switch off pressing the button, it switches the Kindle on again!
And stranger thing : sometimes when I open the cover, the Kindle is still showing the text, not screensaver... but the backlight is totally switched off! For those who absolutely want to be able to switch it off, can be interesting
More seriously, do you know guys where the magnet is supposed to be? I could try to remove it or something...
