...but 0 stars for reliability. After 2 years of use, my son's TI-83 Plus is kaput. He cannot see the print on the screen (and, yes, we tried all the "2nd/up" contrast settings, removing the batteries and resetting steps, etc. Even called customer service). They say his silver screen is shot. Only $58.00 to replace with a reconditioned calculator!!
I am inclined to say it's quite a scam that every student in his school is required to buy a TI-83 or 84, because I would love to try a HP to see if the quality is any better. : (Get more detail about Texas Instruments TI-83 Plus Graphing Calculator.
