I came into ham radio when Bomar, were cheap, for  Motorola Dispatcher 2 m radios, at about $5 ea, and 
the gold standard, guaranteed to work and be dead on freq was International crystal at probably triple that,  out of  Oklahoma..
Well here is a great history of that technology industry as a very interesting and detailed narrative.
Probably a link worth posting in your club newsletter.
