It now sits on my desk at work and proves its usefulness everyday.

I'd follow the advice of everyone else on here and wait until you know a little more about the situation for using the calculator during tests. When you do decide you need one though, I'd highly recommend the 89.

PS- My calculator was a "regular" TI-89, not the Titanium edition. Many of my peers had the titanium edition, and I'm not sure if it has more features or not, but I liked the look and feel of the regular one much better.

I am also a big TI-89 fan. If my memory is correct the differences between the 89 and 89 titanium are the same as the differences between the 83 series and the 84 series. New interface, more ram, better screen, new case.

I would definitely reccomend buying the 89. I use mine all the time. It is not allowed in many of my classes but i still use it to check work and I use it any time I need to do math for projects or labs. My 89 has lasted me since junior year in HS.

The only reason I would reccomend waiting to buy it is that many teachers in HS only know how to use one type of calculator. Usually the 83 series. If your teacher uses the calculator in class then they may not be able to teach you to use yours. This is not a big concern since the 89 can do every thing the 83 can and then some. However you will need to learn how to use it your self.
