<p>Well the title is self explanatory!
I want one that wouldnt be banned by college exams and is preferably cheap..or if not..atleast a good deal(worth the price).
thanks!</p>
<p>I would like to know this as well!</p>
<p>The TI-89 Titanium can do (pretty much) everything, though it may be banned in lower-level college classes.</p>
<p>The TI-84 Plus/TI-84 Plus Silver Edition are great calculators, too. They’re usually not banned on any tests that allow graphing calculators, but they’re not nearly as powerful as the TI-89 Titanium.</p>
<p>TI released the NSpire last year. I haven’t used one, but it looks pretty cool. As far as I know, the NSpire is comparable to the TI-84’s while the NSpire CAS is comparable to the TI-89. You might want to see if anybody posts a review about the NSpire.</p>
<p>@314159265- Thanks a lot for ur input…i’ll keep that in mind! 
By lower level college classes do you mean intro classses? coz i read somewhere else too that its banned…but i really liked the look of it.</p>
<p>Anybody else willong to write a review for the NSpire??</p>
<p>I’m guessing that the TI-89 would be banned from classes like Calculus I and II where many of the problems can be solved if you know how to use the TI-89.</p>
<p>The NSpire is nice but it has a large learning curve. The regular NSpire has an 84+ keypad so you can use that if you’re having trouble with the NSpire one.</p>
<p>The NSpire has a handy menu and I wouldn’t have found many of the features without it. My favorite one is solving variables.</p>
<p>If the lower level classes ban the TI-89 Titanium, I’m assuming we’d have to get another graphing calculator, say the TI-84 Plus, in addition to the TI-89 Titanium?</p>
<p>(I’m also in the market for reusable calculator)</p>
<p>^Yes. </p>
<p>And OrangeD00D, the “solving variables” feature you mention (I’m assuming you mean it can solve equations like x^6=4587253) can be done on the TI-89, too. The NSpire CAS (not regular) and TI-89 both have CAS’s–Computer Algebra Systems–which allow them to solve equations.</p>
