I also came across a Ranco temp controller on ebay. I think I'm going to build my own unit, which is going to end up costing the same or less than the Ranco controller, I'll be able to control everything, from heaters, to lights, to auto feeder, motion detection - incase of a jumper, and it will alert me by cell if something doesn't trip, or does trip http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=50
