would it be worth trying to sell one of these

 

Yea if someone want one. They cant be had new anymore

 

I would think they are quite sought after.
Is it fully funtional eg does the display work ok in cold weather? Mine started to play up last year so replaced it with a Scangauge, which is not as good. Still have the PSi3 and use it for an occasional AFR check (which I can't get the Scangauge to display)

I could be interested in it if it is in full working order.
