    Any scale that's getting into the milligram resolution or better range is going to have some susceptability to static, as well as air currents. You can make a little enclosure out of cardboard to help deflect air currents.

    I've had good luck with the cheapo ebay digital scales. The two I bought 5 years ago read a set of certified weights nearly dead on. Not bad for $25 scales. The only problem is the one that reads to 1000g is smaller than the one that reads to 100g so you need to have a light-weight weighing boat to measure large amounts on it.

    Another vote for Ohaus triple-beam balance. For what I have spent on cheap digital scales that last only a short time, I could have nearly bought an Ohaus and given it to my son decades from now.
    f/22 and be there.

Acculab has gone out of business as of January 2011, acquired by Sartorius Group. Sartorius makes a similar line of reasonably priced accurate scales. The prices seem comparable to the old Acculab line. I can vouch for Acculab, but I haven't used Sartorius scales so I can't say if they are comparable in quality.

    Here are some examples: http://scaleman.com/catalogsearch/re...q=sartorius+ay
    I have a Acculab V-200 with 0.01g accuracy that I'm very pleased with.

    I have played with a couple of Digital Scales now. My wife decided to get a real fancy one for her Kitchen, (What else who you expect from a retired engineer) and found that her reading seem to differ by the phase of the moon! the lower accuracy one she used to measure the Dog's Food tends to drift for about 20 minutes when started up and so she leaves it on all the time. I have a similar one to the "dog food" scale for my Darkroom.

    All three are from "My Weigh"

    Note that the electronic scales are calibrated by putting a SPECIFIC amount to weights on the scale. When I bought my first one I only bought one of the weights thinking that it was just used as a check, so had to go back and buy another weight. Order the set that the scale you buy needs at the start.

    Looks like I'll need to take extra measures to isolate that scale from its environment. I don't dare even breathe near it!

    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

    Ugh, got a call yesterday from Ohaus that their website was out of date and the scale I was ordering was not available as a refub. Order new one today and am sure I will be happy with it. Bill Barber

    Refurb inventory changes daily.
    They may only have one or two refurb units at any given time, and when those are sold... no more until a new batch is finished.

    Glad you ordered a new one. It will last for many many years.
