[rescue] Interest in Heathkit kit?

I don't know to what extent this is appropriate for this venue. If
not, just tell me and I'll shut up. (It's not really computing, but
I've got a Heathkit IM-1202 digital multimeter I built back in the
'70s which I want to get rid of as part of decluttering/downsizing. It
was my workhorse multimeter for a long time, but I never use it these
days - I've got a Fluke that's a substantially better meter in
basically all functionality respects - and, while I do have a certain
nostalgic attachment to it, that attachment is not enough to push it
into making the "keep it" cut.
It works, at least superficially. I plugged it in and turned it on.
It lit up (it's got 2=-digit display, using nixies for the 2 digits and
a plain boring neon lamp for the = digit, and other neons for +, -, and
over-range indicators). I put it on 200ACV and measured the local
mains voltage; it gave me 124, which is a little high but only a little
(the Fluke says 118). Resistance gives a few hundred K between my
hands, which is roughly what I'd expect (the Fluke agrees). I have a
fuzzy memory that I rewired something internal; upon opening it up, it
looks as though I just jumpered the two measurement jacks (when
assembled per instructions, it has one jack for voltage and one for
current/resistance). It would be easy to remove that jumper.
It comes with the test leads - one ground lead with an alligator clip
and one conventional test lead with pointy metal tip - and its book,
which latter contains assembly instructions, parts lists, schematics,
theory-of-operation, and suchlike. (Hmm, I wonder if I should scan the
According to a quick search on my work "smart"phone, other IM-1202s are
going for roughly $100-$150 on epay. That's not enough to make me feel
it worth the bother of finding someone to list it and suchlike; I'd
rather it go FTGH here to, well, a good home. :-) It might make a good
first multimeter for someone starting to play with electronics.
