Way better than the TI-84 Plus CE; I also really like the UI since I also really like the TI-86 UI. Brother damaged it -_- |

Bought off E-Bay from someone listing it as a TI-86. For sure paid less than I otherwise would have, given that it's in almost perfect condition. |

Second Christmas calculator. Really nice to use, and I've convinced a number of classmates going into various fields in college where it might help to buy one. I hate how often it crashes. |

Funny impulse purchase. There's no serial number or anything on it, and as far as I can tell Catiga doesn't really exist on the Internet aside from selling this and the other model exactly. |

This is actually my second TI-84 Plus CE. My first one was an early revision, but was washed out after the teachers required we leave our stuff outside during a tornado watch. |

First calculator I bought for collections' sake, rather than to use. I do find programming for it fun and have written my own statistics suite for it. I also intend to, at some point, look at some assembly programming to add arbitrary x-value calculation for the graph math features. |

A very clear predecessor to the TI-86, and while it's missing a lot of what I like about the '-86, it's still very nice, and it has the boxy TI-81/82 shell that I like for some reason. |

Bad connection between power and MB means it loses RAM on the slightest bump. |

Worse condition than the other one, but since I'd rather have that one, and can't return this one, even though the other one was supposed to be a regular -73, I have two 73Es. |

Turns on but doesn't want to stay on. Will probably need repair, but otherwise works properly.
Seems to be an issue with the batteries not staying in, not an actual hardware issue. Marking as working. |
