I tried to sell one of these on here back in december 2008, dont know why it didnt sell, maybe the price, I was asking double what your asking. here
This is a Bargain people, an initial outlay of £20 could save you a £60 fine and 3points. So the first time it actually "saves you" you will be £40 up.
There is a bit of info on my for Sale
thread about getting free updates for it aswell.
