Should I get a TI89?

Yes. Get in your car, drive to the store, get out, and buy the TI-89. I love mine. It has a steep learning curve, but the journey to mastery only lasts several weeks (sleeping with the 89 will speed up this process). It is so much more efficient than the 83 on higher level math (Calc +). I wouldn’t recommend it for anything less, though.

Try solving derivatives and finding the area under a curve with both (83/84 and 89) and see which one you like.
