Finally, you can sell it for around $80 when you're done with it.

I also don't know why anyone would recommend the TI-30IIS. Its keys are terrible--if you don't watch the screen while you input stuff, you'll make mistakes.

1. Get the TI-84 Plus, while other brands are less expensive, it's hard to follow along in class (and some textbooks) if you are not using Texas Instruments. (I had many students coming in to borrow a TI and complaining about using their Casio's because of the button layout. It makes a difference!).
2. Do NOT get the ones with the rechargeable battery; yes, it sounds good, but if the battery sits (over summer) uncharged, you might have a hard time getting it to recharge. You also need to remember to carry around the charging cable *and* be able to find a place to plug it in while it's charging which is not so great in the middle of class.
3. I personally wasn't impressed with the color screens, they seemed to have more problems and I couldn't fix them.
4. If you buy a "old-school" black & white screen TI-84+ for a good price, you can resell them for about the same price. Our high school had calculator models from TI-80 thru the TI-89, some of the older ones were over 20 years old and still going strong. I had to junk/recycle more of the new fancier versions.
5. Be careful of AA/AAA batteries - the cheaper ones will leak (use white vinegar on a cotton swab to clean the calculator, then follow-up with another swab dipped in rubbing alcohol). Best batteries in my 10 years were Energizers and Amazon Basic; worst ones were Duracell (as well as the Costco Kirkland brand which are made by Duracell).
6. If the calculator turns wonky, do a search how to reset it. You can also use a Mini-USB cable to connect it to a PC, and use Texas Instrument's TI-Connect [ti.com] (free program) to reinstall the firmware (or update it).
7. Generally... Geometry students need a TI-30XIIS; then Algebra, Calculus, and Stats students need a TI-84+
(eta) 8. Use a *paint pen* to put your name and phone number on the back of the calculators! If it's left behind, it's almost as good as gone (sold for $); paint pen is harder to remove, in fact permanent marker will wear off over time as well as easily removed.
(I'm a mom to a son who was Math Team Captain, completed Calc III his high school junior year and went on to earn a college Mathematics degree (minor in computer science). He used a TI-89 thru high school; college he used his TI-89 and his Scientific)
