Texas Instruments - Scientific Caculator Review

I have an older TI.  I have the TI-82 and really like it because I just recently went back to school and it still works after 10 years.  I would reccommend this to anyone that needs a graphing calculator.  I would highly suggest this calculator for anyone who is going to take an algebra class with algorythms.  I think this calculator is kind of expensive but it is worth it because they last it seems like forever.  I have never had a problem with learning how to run this calculator.  The book that comes with it is very explanatory.  It is a great investment for a student of any type of education, taking a math class.
