QRD1114's, they have a infrared LED and photo transistor together in one package.  You need to make a simple circuit and use a microcontroller to read it.  This one already has the parts and is ready to use: http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/List/1/ProductID/100/Default.aspx?txtSearch=line+sensor&SortField=ProductName%2cProductName
