Philips Speech Mike Pro Plus Voice Dictation $450

New out of box Philips Speech Mike Pro Plus Voice Dictation retails for $450+, this was my father's and I can't find the box anywhere or any related accessories. Not sure if it even comes with any. Record dictations directly onto your PC with the recording function buttons. The scroll wheel and the trackball allow you to precisely navigate through all of your PC screens. The four function keys and two trigger-style touch buttons on the rear of the unit are fully programmable.
