I have a Heathkit EC-1 analog computer in operational condition with
the patch cables, assortment of caps and resistors plus the operating
manual. I have entertained selling this (robbing Peter to pay Paul) to
help fund a 1939 pre-war television acquisition. A dilemma. Should I
part with the EC-1 I doubt I will ever find another. As toward the
value of the EC-1 I don't have a clue but would like to know what
anyone else thinks a fair price would be.

I used to collect coins when I was a kid, and the Blue Book (wholesale
values) and Red Book (retail values) were my bibles. Coins had a pretty
good grading system, and you could find fairly reliable production data.
I don't know of anybody that has tried to do anything close to this for
computers.

eBay and other online auctions are probably the best gauges of prices
there are, because they represent fairly efficient markets. In fact, some
online auctions that move their own inventory do regression analysis that
tells them more or less what price they can expect to get for any given
item. If somebody were to do the same analysis on person-to-person
auction data, that would be a very good starting place for a price
guide (especially from an auction like Haggle Online that also stores
condition, make, and model information :-).
If you only look at one or two anecdotal transactions, that doesn't tell
you much.

The real question is what value does your insurance company place on your
collect. My guess is that they would value an Apple 1 based on a twenty
year depreciation starting with a $666 basis!
BTW, if, hypothetically, I were to find somebody willing to sell me a
Heathkit EC-1 analog computer in good condition, what value would you
experts assign to it, and what would you base your valuation on?
