Cabelas XT-1500
I have been using the Cabelas XT-1500 scale for about a year and it seems to be pretty good. You do have to let it warm up a few minutes and check the tare once in awhile, but it seems to be accurate. One thing about these scales is they are not too far off in terms of range and accuracy demands from laboratory analytical balances which start at $2k. They are obviously not the same quality as these balances.
The point I'm trying to make is that these balances are weighing very small masses( 7000 grains/per pound and we want accuracy to .1 gr). They are very sensitive to air currents, vibrations, temperature fluctuations and in some cases, supply voltage changes. Also sources of static electricity can cause them to read very erratically. They also generally will not handle overloading well. You need a very stable, level bench (or be able to level up the scale) to put them on. If your bench isn't really solid you might try buying a granite surface plate from someplace like WoodCraft and put it on top of some closed cell foam. This will decouple most vibrations between the bench and the scale. If you think air currents are causing problems build a draft shield around three side and the top. Cardboard will do.
