I have found in the bureau a almost pristine 1st generation handheld game console. I also have the originl instruction leaflet that came with the game, but alas no box.
I've had a look at the bay & they go for upto £100+ (with box)
Looking at around £30 for it + delivery charge (2nd class recorded included in the price) of your choice)
(ie 2nd recorded - free, 1st recorded - add 30p or special delivery - add £5)
BT is preferred payment for this or paypal gift is second choice
