Amazon product: Casio fx-9750GII Graphing Calculator, Blue
There are lots of functions to learn but my grade 11 son says he loves this as it allows him to do some of the work in only half the clicks as other students with the pricier TI-83 or 84 graphing calculators. He reports that he can use it well despite how intimidating all the functions look. So far so good with it, we have had it for about a month.
