Most of the ebay listings I saw (in the US) were for used equipment. Did see a new one for $550.. Do these come with a date of manufacture so one could verify how old a new meter is? Does it matter? Thanks.I have always wondered why the prices on ebay were always higher than the online store of a company and I am talking about new unused products. I tried today to open a corporate account and calculated that the service cost together with the paypal cost is about 20-30%.
