Yamaha DGX505

Overview
The Yamaha DGX505 is an electronic musical keyboard with 88 unweighted velocity-sensitive keys, a memory card reader, and a USB port. It has no MIDI port, although apparently the USB port provides much of the same functionality (presumably a computer is required). It comes with a bench and stand (looks like fake wood veneer over particle board).
