Try eBay.  People are always selling groups of several counters.  I think
that was an old civil defense package, with three counters (one with a
probe, two with internal GM tubes), a bunch of radiation badges, and a
badge resetter.  The price usually goes to around $70 for those sets of
three if you watch them for many days, so if the price for three goes far
higher than $70, wait for the next batch.  Try these:
