Thank you for this informations.
I know this seller (I took some CPUs in the past, too), and I agree with you the prices is not cheap.
But some chips is interesting. I am going to try to negotiate realistic prices (for my budget, I am not Rockefeller).

I have some problems with estimation of my chips.
I have no inea how to compose the adequate prices.

Is only a your valutation.
Generally the rarity and the value of a chip is in this order:
White ceramic body
Ceramic body with goldcap
Ceramic
Plastic
But this isn't a rule, for exemple I looking for an Electronic Arrays EA9002 for a long time and this chip is in a plastic body, if I will find one surely I will pay a price higher than a normal white generic ceramic chip (like Fujitsu 8086 or 8088).
So we return at the first point, it's a your generic valutation based on your experience or based on a your expectation.
In all cases I hope you will consider my offer.
