You've got me wondering now, HD. Coming in and out of vogue, desire, is attached to market value for sure. But do unreasonable prices cause guns to go in and out of fashion? Consumerism, advertising, may weigh more heavily than practicality among the more easily influenced. Our bigger-is-better culture doesn't seem to have penetrated to the same extent overseas. My guess is most members here acquire what is most practical for the mission. The big market cycles on me-too emotion like skirt lengths.
