Hi,I am watching one in australia on ebay with 2 game carts presently up to $102.50 aus dollars which is about 40 pounds in uk.I would prob pay about $50.00 aus maximum.I have 6 units,but i was lucky when i started lynx collecting about 6 years ago, my local computer store was giving away a free refurbished unit and pouch in box when you bought two games at about $20.00 aus each,so thats how i ended up with so many.I watch e-bay all the time for lynx and am amazed at the way lynx items are quickly snaped up,I dont keep my boxes but i always buy games with instructions.
