I have an AME Port Extender for the HP41. I picked this up about 10 years ago with a bunch of other accessories and am thinking of selling it. I can't find any others that have sold. Any ideas on value? I'm not looking to get rich but I don't want to give it away either.

I used to have one and sold it on ebay several years ago. Over the past year or two I've seen one or two pop up on ebay. IIRC, they go for about $100. For items like this that show up very infrequently, the sales price can be wildly variable.

Thanks Dan, the value changes with time, sometimes by the week, atleast on ebay. I haven't followed the market for several years and haven't ever seen any for sale. Liqudating some of my collection and don't want to give it away.
