Appropriate Connector/Cable for Expansion Header

Hello Everyone,
I’m researching using the beagle/panda board for an embedded ultrasound/computer vision project. I’ll need to integrate an analog codec (via SPI) with the board via the main expansion header, which according the datasheets is a .100" pitch 2x14 connector. The only problem I’m having is finding the appropriate connectors/wires. 28 pin ribbon cables/connectors do not appear to be standard and are not kept in stock at digikey or mouser (special order or backorder only). So, does anyone know where I can get an appropriate expansion cable/connector for these boards?
Thanks for your help ,


You can always just get a 30 pin and not plug in the two left over pins.
