I got my ti-89 titanium brand new off ebay for $127 shipped. Higher than what you want, but it is a nice calculator which will last you a long time

I got my 89Ti for $100 shipped. It arrived in perfect condition.

DARN YOU! :|

I had a TI-86, and then got a TI-89 when they first came out. Was allowed to use my 89 in every class. A friend had the 92 and was not allowed to use his.

Do note though that many lower level college classes (and most HS classes) will not allow anything over a TI-84 as they will basiocally solve the entire problem for you.
When I was in HS and College they allowed anything that wasn't QWERTY (i.e. TI-92), so anything up to and including the TI-89 was fair game.

Never understood why those things cost so much. Old technology
Most of it is simply because TI is the only company out there that makes them.
HP and Casio both make graphing calculators. However, the HP calculators are obscenely expensive.

They're expensive because they are low-production, niche-market products. The only people who buy them absolutely need them.

Why does your school think you need a graphing calc for geometry? 😛 They should tell the teachers to teach you math instead of how to use a calculator...

Yes, other companies *make them*, but TI is the standard. If you have another brand calc and the prof is explaining how to do something, you will not have a clue as the interface is different.
If you can't figure out how to put the equation into a different calculator than the example, you should fail the class automatically.

When I was in HS the school issued Casio calculators and gave all demonstrations on them. I had a TI-85 and the school provided zero information on it. They used the Casio because the Casio could graph a conic section directly, whereas the TI required that you manually split the conic section into its two halves and graph each half. Even with the additional requirement of having to manually split the conic equation into its componant halves and enter two equations into the TI, I was faster than anyone on the Casios. (Granted, the Casio calculators were crap and took over 4 times as long to graph an equation than the TI-85 did, so I was always the last to have the equation into the calculator but still the first to have the graph.)

Anyway, I drifted away from the point, which is that you should be sufficiently able to understand the underlying mathematical structure that the brand of calculator being used by the professor or teacher is completely irrelevant. The only way you would have a problem from using a different calculator is if you were blindly copying the teacher/professor and in that case you're not actually demonstrating any knowledge so what's the point?

OP, Ill see you a TI 89 with USB connector to computer for $100 shipped if you're interested.
 
the only reason graphing calculators are used in high school is to familiarize students with them. i havent used any of the advanced functions since AP calculus. in fact, the only reason i would use a TI-xx is because of the large screen (you can see whatever it is you're inputting)
 
the Ti-89+ is a wonderful tool for an engineering student, but Matlab is and always will be better. too bad it isn't as portable.

Well, if he ends up taking the SAT, the TI-89 will not be allowed, either. You don't want to bring one of those and end up without a calculator to use on the test. Therefore, he should probably buy a TI-83 or TI-84.

Can't hurt 🙂.

That's mainly why I use my 83 instead of my 30 most of the time (the main exception being Academic Decathlon, where graphing calculators aren't allowed). The "graphing calculator exercises" we do in my precalculus class are wastes of time, though, and I've not seen a reason to learn how to program one either.
 
The Godfather -- yes, the Ti-89 will solve variable or symbolic equations for you. It also works natively with fractions, radicals, and imaginary numbers.

It also displays everything you enter like it should look -- the so called pretty print feature, which makes it a lot easier to make sure what you entered is correct. It does symbolic integration and differentiation, which is a big deal once you get to calculus. It will also do unit conversion, which can be a big help in chemistry and physics.

Thats awesome!

I'm not a very good test taker. I understand the material fully, but when it comes to tests all i get are B's and i'm not flattered. Maybe that can be of help.
