Algebra and lots of calculus can be done on calculators too. TI-89 was a great friend in pre-calc and calculus during high school. TI-84 plus got me through calc 1 last semester, its a big help in calc 2 but to really save time I got the TI-89 all over again. Some of the big stuff slows it down but it can do a LOT for you. for high school the 92 and voyage 200 aren't practical because you can't use them on any of the big tests.
Just don't get to the point where you need the calculator to do everything, there's tests with no graphing calculator allowed. In those cases a scientific calculator that can give you exact answers is awesome. I use a casio fx-115es. Does definite integration and will give you values for a derivative at specifc points on a function.
