HP 320K

A TKL keyboard running Membrane switches. A wired connection and single-color backlighting round out the spec sheet. Switch feel is personal; try the switch type before committing if you can. TKL frees mouse space without sacrificing the function row.

Its $12.89 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest keyboard deals from multiple stores.
