I just wonder for how much longer will Texas Instrument calculators cost an arm and a leg..... "This new and affordable $250 quantum computer can compute septillions of calculations per second; it is the biggest leap in performance ever witnessed in computing. It can solve the most complex mathematical problems instantly and with our brain wave add-on, you can think of any mathematical equation and it will simultaneously be entered and solved in the computer. Each step will be fully explained and showcased in a high definition hologram display. We also have a caveman-esk computer on sale, its a TI-83 calculator. Its only $95! It is still required by math courses, life sucks, deal with it."

Remember to share the love! Give reps to the OPandthumb up the deal.
Don't know if it's worth the extra cost ($18), but here is the TI-84 Plus Silver Edition calculator at either Walmart or Amazon for $95 with free shipping. There's also a comparison chart in that post that shows the different models and the features/memory each provides.
Looks like the main differences are that the TI-84 Plus Silver Edition provides more memory, USB cable, pre-loaded applications, customizable face plates and support for geometry and pre-calculus.
Some folks have talked about price matching at Staples and using $25 of $75 coupons to make it even better. Don't know about success though.
If you're going to continue through math, you will most likely need a Ti-89 once you hit calculus.
imo skip this purchase and go straight to the 89 if your instructor will allow.
I went through Calculus 1,2, 3 and Diff Eq along with a few Calculus based classes with my TI-84+ that I purchased back in high school. Granted that calculators weren't allowed on exams in the Calculus classes, but I still used it often when doing homework.
With that said, it has a built in single integration function, and you can install a double and triple integral one, which I have although I haven't used it much. I'm not sure about derivative function, but I'm pretty sure you can download one. Actually, I'm pretty sure you can install most of the functions that the TI89 has but the TI83/84 doesn't. The main difference I saw is that the TI89 has a nicer graphing function.
