Dell KM300C

This is a TKL keyboard running Membrane switches. A wired connection and single-color backlighting round out the spec sheet. TKL frees mouse space without sacrificing the function row. Switch feel is personal; try the switch type before committing if you can. At $19.98 it sits in the budget keyboard bracket.
