I have a classroom set of 82s and that happens to be what I use at the overhead. Most of my calculus students are buying the 83. Although the 85 would be fine, I will not give any class time to it and I really miss the tables (although I know you can write a program for it.) We will probably go completely to the 83 eventually. One interesting difference I have found in the 82 and 83 is y = x^(2/3). You have to write it as y = (x^2)^(1/3) (or some variation of this) to get it to graph negative numbers on the 82. The same problem can be entered directly on the 83. There are several similar type situations. I am not particularly eager for my students to get 92's. I wouldn't mind having one for the overhead for some demos. I,too, hope that they will not soon be approved for use on the test. It would change the test too drastically.
