I believe I had an HP48 back in college, and I've been using an HP49 in grad classes through the years. Either one can easily carry you through Calc 1 and 2, Trig, whatever. They can solve most any sort of equation you can throw at them. Even the HP48 was better than the TI89, the HP49 just kills it by comparison.
I think I heard HP stopped all calculator production though. You might be able to find some somewhere still, but they were like $200 when I got mine... Plus you wouldn't have the same interface as everyone else.
