Second vote for using the Orion Blue Book.
They are indispensable tools for selling used gear.
There is arguably not a lot of value in their pricing estimates, but I find value in the MSRP info, for the info on the years that the models were sold, and in seeing the full line to see the models above/below yours.
It always helps if you know that the CD player, preamp, cassette deck, etc you are looking to buy or sell was their entry level POS, or the flagship model, or somewhere in between. :)
I sold used gear forever. Ordered the blue book each year.
Towards the end, I used the internet for pricing. Ebay in particular - I figured that if I had to move it used, that was where I would go. Completed auctions told me what I could expect. Blue book pricing became irrelevant.
Back to the original post. More valuable to you might be the replacement cost of that gear. Who cares what it originally sold for.
Hafler 500. Find an equivalent powered new model. Use its pricing.
Same with the others.
