I saw this really cool display of pocket balances (the kind that fold up and can be put away) at the NSTA convention. This seemed to me to be a better way to prevent theft of balances, which is a major problem in many areas because they are used by drug dealers. One school I worked in was burglarized three times in a month for its balances. HBI International only sells to schools and other institutions, and you have to pay with a P.O.
