Hi VIz Vests

Back in the early days it was possible to purchase a hiviz vest emblazoned with OPENSTREETMAP SURVEYOR and the logo and website. I can't remember who organised it but I vaguely remember they were available at mapping parties.
Mine has proved to be invaluable in avoiding those awkward (and potentially hostile) situations where people are rightly suspicious of you taking notes and photos. It has also helped with over-enthusiastic security guards. Other advantages have been: it engenders lots of extra volunteered information from people you meet; it advertises OpenStreetMap; and is great for road safety when cycling or walking. There is one disadvantage however- in some deprived areas you might be seen as representing "officialdom" and engender a hostile response (all I've received are gentle rebukes from old folk accusing me of planning to take away their postbox or bus stop!)
So the question is: would it be good idea to revive supplying these with a preferential purchase price for members and a higher price for non-members?
