Thanks to all for responding. After searching options on eBay, I went to the Ohaus.com website to further research specifications and products and discovered they offered refurbished products with a 90 day warrantee. I bought the 760-00 scale at $87.95 including postage as opposed to $153.75 with free shipping on eBay for a new one. My expectation is I will be happy with the refurb and have an extra $65.80 to spend on chemistry and supplies. I feel very comfortable buying a refurb from the manufacturer. Bill Barber
