seems to be about a bazillion ipad cases out there, so would like a bit of a reccomendation from actual people on which ones are good and/or which ones to avoid.

I would like the following features:

covers the screen when not in use and has the automatic wakeup function
be able to stand the ipad at both shallow and steep angles
be able to stand the ipad in both horizontal and vertical mode (something the smart covers don't do)
have a slot for holding business cards and maybe a screen cleaning cloth
have built in bluetooth keyboard  (last one not a deal breaker, but would be nice)

colour not really important, just a neutral brown, black, grey is fine.

material not important, but leather is always nice.


price I'm guessing around $80-90, but not a major issue if it is more

any help would be much appreciated.
