USB And PS2 Ports On KVM Switches?

An Anonymous Coward asks: "I am regularly working with multiple computers and have given in to the fact that I need and will buy a KVM. However, I am in need of a device that can switch both standard PS2 (mouse & keyboard support) and also USB. From my searching I have found KVMs with Monitor + USB or Monitor + PS2, but not all three. Does anyone know if such a USB + PS2 + Monitor KVM exists?"
