balance scales

I have been researching electronic balance scales for use in measuring ingredients for titration and brewing. The Boreal balances at Edmund Scientific caught my eye. I need some advice as to what range of scale is most useful. I think the lower limit probably does not need to be lower than .1 gram. What should the upper limit be?
500g, 1000g, 2000g?
I will also want to use the scale for measuring moisture content in wood for a dry kiln but that might be a topic for a different forum..
TIA
