I have a TI-89, it is superb. Go for an 89, or a TI-91 or TI Voyage 200. I've typed out a response twice and my explorer has closed when I've tried to send it (yes I copied the text I wrote but I seem to have lost that too) so I can tell you more why I like it, but I'll have to do it later.
Where do you go to school?
