I do not have a calculator that does matrix stuff that would be great for my classes this semester. I don't want to spend $100+ on a graphing calculator since I use MATLAB at home strictly now. I am looking to solve simultaneous equations, matrix operations like det,eigen,mult,...etc

Any help would be great!

The TI line (83, 89, etc.) handles matrix math just fine, and some of them go for under 100.
 
My Ti-89 is still a classic. The best you can get for the money. I won't bother with anything below Ti-89
 
I was kind of aiming towards $20-30...

ebay? I haven't seen a graphing calculator under $80 in years, and I don't think non-graphing ones handle matrices.
 
uhhg, maybe I can borrow one. Thanks everyone.
 
I just bought a TI-86 on craigslist for $30. It didn't seem like that was an exceptionally low price or anything, so you shouldn't have a problem finding one in your price range.
 
See online matrix calculator http://calculator-online.org/s/matrix/
 
TI-89 is good but price differs for place to place better to get an used one it would be better
