Or go to www.ebay.com and search for "1g electronic scale". Info is below. I have one of these in my basement, one in the hangar, and another in the kitchen. For $5.49 and free shipping, you can't go wrong. They work, are repeatable and I'm happy with them. The 1g resolution is invaluable for getting precise amounts of small quantities.
