we have one Parallax programer for sale. Comes with modules for PIC16c84,71 and 74. Purchased less than a year ago and used three times. We have just purchased the Microchip PICMASTER and this is the only reason we are selling one of the Parallax systems. I have no idea what Parallax sells the used systems for, but suffice to say we will probably beat their price. Drop a line if interested. Fax # 1-905-689-1815
