I have Joanna Jet's Jet Set 1 and 3 on video and Jet Set 3,4 and 5 on dvd for sale. As they have come from Joanna's company, they are US specification ie NTSC for the videos and whatever the region is for USA.
If anyone is interested in them, let me know. I would prefer to sell them on the UK side of the pond to cut down on postage costs.
