I picked up a sort-n-save bank at a garage sale for a dollar. Put thre coins in and they are sorted by denomination. The task of rolling is made easier too because the coins are sorted into tubes and you just push the wrapper over the coins.
Don't buy a fancy machine driven one. A cheap and simple one is best. In the meantime sort your coins by hand. Why pay coinstar?
