Cual es la razon para invertir 35 dolares en tu fx-991es, si la calculadora fx-991ex vale apenas 20 dolares y tiene 135 funciones mas ?

Me gustó más su diseño, la utilizo como calculadora de bolsillo no programable únicamente , (utilizo una programable para ingeniería). el precio estaba en oferta cuando la compré, me costó casi lo mismo y me gustó más.
