An option with far fewer cables is the RecorderGear PR200. It records your conversation via Bluetooth. The call button in the middle of the device can answer calls on the Bluetooth-connected phone. Hold the PR200 up to your head to talk and listen, as if it's the phone. It also features a USB end to quickly access recordings on the computer.
