I have a HP 49G+ and it's great, much better than the previous models.
It's funny how you don't find Texas calculators here in Brazil, even though I heard they are much better than HP's. A professor of mine has an old TI-something that looks like a spacecraft (you need both hands to HOLD its HANDLES, and it actually looks like you're playing some video game) and it is amazing, much more capable than my HP.
Cons:
My calculator has the annoying habit of randomly changing modes from radians to degrees and vice-versa, all the time. Forget about it and start getting weird results and bad grades!
