<p>Where can I get a cheap TI-89?</p>
<p>thanks.</p>
<p>Ebay? .</p>
<p>I have no clue...</p>
<p>but out of curiosity, what do you need a TI-89 for?
TI-83's are still what's used the most in high school classrooms (i'm assuming you're in high school - as this is the high school forum)</p>
<p>TI-89 rocks. I've been using it since like 7th grade and now I'm in 10th grade. I wouldn't give it up for anything.</p>
<p>they didn't have it out in 2002... did they?</p>
<p>They came out in 2000. I know this because my math tutor is a math psycho and he has math stuff all over his classroom, including a huge painting of the TI-89 on his door with the year 2000 and the artist's signature at the bottom.</p>
<p>I want one for my math classes, and since I'll be doing math my whole life, I'll be using it then too. I've been using a TI-83, but it sucks. (anyone who is in higher math knows that.) I should have gotten an 89 instead, but i didnt know that they existed then.</p>
<p>Anyways...should i buy a ti-89 titanium or just a regular one? on ebay i think you can get an 89 titanium for about $90-110 give or take and you can get a regular 89 for like $50-70 give or take plus shiping. i'm kinda leaning toward a titanium, but $110 plus shiping is still alot of money to me.</p>
<p>Just get the regular one. Although the titanium has preloaded features, you can easily download those features into your normal TI-89 from the Texas Instruments site. There's really no difference between them, I just wanted to get a calculator of my own instead of continously borrowing one from my math tutor, and behold, Titanium is on the market. The home screen is exactly the same.</p>
<p>black market ;)</p>
<p>Cheapest way? Win some math award where it's the prize- our school gave them out as part of some award last year.</p>
<p>I got one for Christmas in 5th grade: sad, isn't it?</p>
<p>Wow...so much about calculators I never knew about.</p>
<p>I find TI-83+ plus to be perfectly useful in my math class - I don't know what defines "higher" math - but it's fine for bc calc...</p>
<p>TI 89's just make you lazy, 83+ has everything essential in it</p>
<p>see? another asian who agrees with me... don't get the 89...</p>
<p>89s are required at my high school...so are laptops with mathematica. Does anyone else go to a high school that uses mathematica on laptops to do math?</p>
<p>Get em on ebay, its cheapest there. Or go to you local store and see if there are any open ones that have been returned(ripped package/missing manuals = cheap), you may get one for cheap :).</p>
<p>Haha, I remember one of my friends had an idea about getting discounts at Best Buy for the titanium(they've marked down ti-89s with missing manuals before). He was going to have another one of his friends buy a titanium, take out the manual, and tear up the package a bit, and then return. Then he'd pick it up the next day at a lower price :-p.</p>
<p>But I guess thats pretty wrong morally.</p>
<p>and the friend wouldn't get a full refund either...</p>
<p>I'm pretty sure you get a full refund if its within a few days right? You may have to include the manual, but I don't think they would take off money if the package was just ripped. I remember it when I returned my mp3 player :).</p>
<p>I absolutely love my 89</p>
<p>it hasnt made me that lazy but it is so much more functional. I love how it works like a computer (always on insert mode, can easily scroll through/cut/copy/paste old answers and problems etc) and pretty print makes everything so much more fun.</p>
<p>I dont like the titaniums though, I had to search high and low for a new 89 because they only sold the titaniums. The classic case has a design that has proven the test of time and feels good in my hands (not to mention matches my 83+) while the 89Ti feels chinsy and the buttons are not as nice.</p>
