If you don't need the CAS, take a look at the TI-86. It has a nice screen (IMO better than the ones you've mentioned and any 89) and it's a great calculator that excels at number crunching (done right). The keyboards in the TI graphing calculators are decent, no debouncing problems, rubber domes work forever -same technology of older Casios-, and they can be taken apart for cleaning easily (no rivets).

Dave, check out Equation Writer for the TI-89 at the TI site for an alternative entry mode. Yes, it's a CAS calculator focused on the CAS part. I think they made the right choices for a 50-key version of the 92, it's just not obvious at first sight. |
