I've just bought a Nexus 9 and like the look of those Folio Case/Keyboard but begrudge paying £110 for them.

Can anyone recommend an alternative?
Wow, 3rd of the price of the tab itself. I can understand why you want an alternative. Usual suspects, Logitech and Belkin not got anything yet? I have a Tab S 8.4 from Samsung and they do have an outrageously priced OEM folio and KB case but Belkin has some $30 alternatives. Bluetooth is the price killer.
