Thanks, Steve. Yes, I'm familiar with the adage that, "The value of a thing is what it will bring," or "A fair price is what a willing buyer would pay to a willing seller," I was just hoping for some way of deciding what my side of that should be.
My Dad used to look at what was happening on eBay even when he wasn't actively looking for something, and would be able to say, "Oh yeah, I saw one of those go for $xxx on eBay last month." I don't have time for that. (Funny anecdote, I remember one time Dad told me that he saw one of our kits go for over $100 on eBay, at a time when we had that same kit on sale on our website for $20; I guess somebody didn't do their research! Oh well, blame it on "eBay fever"!)
I just caught one yesterday, a kit from Dad's collection that someone was interested in, and I found in Dad's list that he had paid about $250 for it a few years ago. That seemed pretty high to me, and I was ready to let it go for less, but then I did some googling and found that kit is still out of production and one had recently sold for $500!!! Obviously, I am glad I did not sell it for $100!
I am just hoping for some hints on how to research prices to avoid "gotchas" like that.
(P.S. I should probably add, I have a pretty good feel for pricing the kits that we produce and others that we regularly sell on our website, the ones that are giving me trouble are the kits that I am selling out of Dad's collection that we have never had in inventory.)
