I lost one too. Well, I didn't lose it, I was sprinting down the side of the busy freeway to retrieve it, when a soccer mom ran it over in her minivan and exploded it into many small parts (and fubar flattened the Hondaline bag rack which is no longer made).

I found one at a motorcycle salvage yard in NE (I think). They would not give me a picture or even describe it to me, saying only it would be
servicable. It was serviceable (as a bag lid) but so scraped up I had to give to my auto body/paint man to make it right. Paid $250 to the salvage yard and $150 to the body man........ and could have had a brand new one (in black) from Honda for $305. Honda shipping would have been free, unlike the salvage yard. Also had to buy many of the little lid attachment parts (interstate tether hookup).
I would not give you the name of the salvage yard I dealt with even if I could remember it. They refused to answer any of my post-delivery inquiries, and so I contested the credit card sale, and they lied like a rug throughout the appeal process.
Just remember what the cost for new is,
before you buy used, unless you are a gifted body/paint man (I am not). Try Pinwall Cycle, at least as far as I know, they will give you pictures and an honest description, so you can make an informed decision BEFORE buying.
Also, I only have interstates, but I like the interstate tether tie system more than a hinged tourer system. I routinely am out riding in high winds when the hinged bag lid would blow closed. The tether keeps the lid down beside the saddlebag, and from blowing away. It is a little trickier to install than a hinge.
