Good Scientific Calculator?

<p>Hey guys, </p>

<p>I'm looking to buy a scientific calculator. I have a TI-89, which I love, but I can't use it on some school exams. I'd like a calculator that does all the things you'd expect, shows many lines of text so it's easier to see what you're doing, and has buttons in the same place as those on the TI-89.</p>

<p>Any recommendations?</p>

<p>Thanks</p>
