<p>choose the one that you are more comfortable with. Both can do math good but i reccomend the ti-89 since i have been using it for more than a year now</p>
<p>The TI-84 is much easier to get used to, and it costs much less. If you're only going to use it a few times, then the TI-84 would probably be better.</p>
<p>I only had a TI-84+ Silver Edition for the SAT I and IIC, and I got an 800 and a 760.</p>
<p>Ti-89 is a great calculator but 199 euros is a rip off, that is approximately 240 US dollars. I bought my Ti-89 Titanium for 150 US dollars.. so i think you should buy from an american retailer if possible (try amazon).. and its about $150 everywhere..</p>
<p>I want to buy it from a american retailer, but it cannot ship to europe</p>
<p>An another option is first sent the TI-89 to my uncle in LA and then he send it to me. But the problem is I think the VAT for import will be high</p>
<p>For both the SAT I and the SAT Math 2c, even a Ti-84+ is unnecessary, a Ti-83 will do. Most people switch from the Ti series to the Casio series in college, so I wouldn't reccomend splurging on the calculator.</p>
<p>if you can, get ti89 for math 2c. it's not about graphing, it's its incredible solving powers that might give you an edge on 3-5 questions.
in college you'd need it only if you major in math or physics.
there is still battle going on between ti89/voyage and casio classpad armies. voyage and casio ae not allowed on sat anyway, and i hear many math teachers in colleges ban ti89s use on tests.</p>
<p>buy it on ebay. every so often certain sellers (bulk buyers?) list them with the option "buy now". means you don't need to compete with the crazy crowd fighting not for the best price but just 'cause the victory is oh so sweet.
use search function to spot such deals.
just make sure it's listed as a brand new in unopened plastic, and even more important - seller has a pristine rating history..
there is always a risk to be scammed, but lately ebay/paypal cracked down on perps. besides, ti89's aren't in such a huge demand that fly-by con artists can make quick bucks before moving on to the next user name.
if you succeed, could you pls let us know?</p>
<p>I bought ti89 in a store on christmas sale (just was not sure if i was going to like it, so i wanted to be able to return; i love it!).
But:
for my friends I bought on ebay
two brand new ti84+ silver for $73 and $85 (amazon price $134),
shipping, insurance, thank you card included.</p>
<p>I bought a lot of CDs on ebay, some from europe,
never had any problems.</p>
<p>i used the ti-89 titanium on mathiic and it saved me a bunch of time because the titanium can do so much more than a ti-84 can (which is probably why it's banned in your school -- it saves you a bunch of calculations)</p>
