Any good Free Graphing Calculators?

[nuka_t]

ive seen the powerone graphing calc and it was pretty cool, but it was 70 dollars. might as well just buy a used ti-83 plus (our math teacher sells us used ones for 75 dollars and buys them back at the end of the year for 60) . does anyone know of any good free ones. im not taking a too advanced class, so i shouldnt need anything fancy, just one that draws basic stuff for trigonometry. one as good as the powerone one would be great though, as i will need a better calc next year for AP statistics.

thanks.

oh, i searched google and came up empty, i wanted t osearch the forum, but i couldnt find a search field.

thanks. i think im going to go with the ti emulator, its only 700ish kb and it seems to do everything a ti can, except its half the size. it would be cool if it had a color screen though. the octave one looks cool, but i didnt see a link to a ppc verison. i downloaded it for linux though and ill try it out.
