I was using a metler toledo(sp) lab scale that was so acurate you could blow on it and it would pick it up. It had a capcity of I think 10kg or something like that. Anyway it wasn't mine and I had to give it back. I went to Staples and they had three models that all had a max of 2.2kg, not really enough for what I need. To make matters worse the only one of the three that weighed in 1g units is a battery opperated one. The other two weighed in 2g and then 5g increments. The one I bought is ok for weighing meals and colubrids but my BP's, Hogs and Rainbows will be too big for it next year.
