Low Cost SBC Dev Kits for Embedded App Training?

SmilingMonk writes "The company I work for is looking to train engineers fresh out of school on embedded software development. It seems to be specialized enough field of interest that it might be helpful for some people to 'get their feet wet' developing embedded solutions on in-expensive SBC ^? s before they are handed off to the product lines. A low cost ($400) full featured solution we recently stumbled across is the eCOG1 Development Environment. Yes, we've been to LinuxDevices, but feel compelled to ask which similarly featured low priced SBCs others have used that we could have our trainees develop embedded Linux applications on?"
