Samsung 7-8" Pouch Stand
It's not a sleeve pocuh, but I love its functionality and cost (in Spain 10-15€). It's available in 3 colors, I have grey and lime, for my Galaxy Tab 7.7 and for my G-Pad 8.3. The Galaxy Tab 7.7 fits perfectly, but the LG is a bit taller than pouch, about 5mm. It fits very good, but maybe the top of the tablet exceed over the pouch.
I recommend you the pouch because its functionality, the size is not a real problem for me.
