Mailarchives (Free borrowing of TIs!)

I just realized something that could be very cool! First go here: http://www.ti.com/calc/docs/loan.htm and read it and the Request Form. Now, my father's a professor at CSU, and he (or almost any teacher in the US) can borrow free TIs! I know he'll probably evaluate one for use in a couple of his courses, but then I can use it after him. Oh, the possibilities... :-) Well, I guess there are advantages to having a teacher for a parent. Now, what model should we request? We're probably going to go with the 89, but I'm not sure. He teaches some very hard stuff, and the 92+ might be the best for the course. I'm excited now!
