Appraisal: Ti89 Graphing Calculator

post #1 of 13
Thread Starter 
I used it for my Advanced Calculus class. It is in mint condition and has everything it came with new. I even have the original packaging! I am now taking more business math related classes and have since moved onto the Ti84 Plus statistics calc and dont use the Ti89. So how much would it be worth? I bought it for $150 new.

$110-$120 shipped. Probably could be a bit more. Maybe $130.

Since the TI84 Plus is around that price too if I remember correctly. And you said you had it in mint condition. So I would say $130 would be good.

Yes. But if you sell it during school year, the price would lower too. Because "back to school" season. The Ti83 plus was around 100 dollars, but then during back to school, it dropped around 20 dollars.

So it isn't wise during then, but it'd be easier to "get rid of".
I have no use for it either. Ti83 plus seems to be "enough" for me. lol
You're going to have to find some extreme engineers, people who do crazy math.

Very true! I was the only one in my class not an engineer or physics major. My class included only 9 people! I only took the class because a counslor told me i neede it for Business. Now that I am transfering to a 4 year, the colleges are adding it as an elective. I did all that work for an elective ! I just wish the counselors knew how to do their job.

lol, I think as you get to higher education, they get slacky.

That's why I am taking some AP classes hoping to pass the AP exam, to probably exempt me from elective classes even if I fail. lol

I think you're best bet is ebay, but I doubt people would but it, if it is above $120, in my opinion.

I think that calculator would be one of the hardest to sell. Usually it'd be the TI83's and 84's. Those are pretty much a hit. Where I live, at least.

I was thinking of selling it for $95 shipped. Hopefully I'll get somebody who wants it for next semester, or even summer class.

Damn, I just bought a TI-83+ for $40.00 on ebay, the 89 is a lot nicer, but it's almost too complicated for me.

i watched the 89's on ebay for a week or so when i was looking for one (decided it was unnecessary)

and i saw 2-3 new ones go for 110+ shipping but that's after watching about 15 auctions

i think 90 shipped is reasonable, maybe 95 if it's in immaculate condition
