Right off the bat I would get the Griffin stand, it looks comfortable, solid, and simple to use. Griffin make quality accesseries for Apple products and this is no different, made out of Aluminum and a non-slip rubber surface to hold the iPad in vertical or horizontal mode, the charging point, speaker, and buttons are obstructed with this design. Overall for $50 is very nice.
GelASkin have some funky designs but out of them all this is my favorite, I really wanted something with the Japanese Flag for some reason. Its provides the right type of protection without making it bulky with an outer shell.
