SD Card to Micro USB Adapter for Nexus 4/7 or LG GPad?

Apple has a simple Camera Connector Kit, is there anything similar for Android? I am aware of the OTG cables for Android, but not really the solution I am looking for - three components - OTG Cable, USB adapter for SD Card, SD Card itself.

Wondering if there is anything simple and small.

I was looking for a tablet and leaning towards the Nexus 7 or the GPad but would love to have the connector kit badly. Otherwise might be forced to go for the Windows Surface RT.
