If a calculator had a color screen, it would almost certainly be more expensive than an otherwise comparable calculator with a blackandwhite screen. Why do you ask for a feature that would raise the price, while in the same breath complaining about a calculator with other added features being expensive?

I actually have 2 calculators. One is an old TI83 since things like TI89 are banned in Trig, but starting in Calculus they are allowed. My TI83 I bought off craiglist for $20. My TI89 is a titanium, and I got it for about $160 at Best Buy. I bought the 89 by mistake, but figured since I will need it in the future I did not return it. It's a really nice calculator.

I have the TI89 previous to the titanium, using OS version 2.09. I already have a color graphing program called Derive 6. Unfortunately, TI has stopped the Derive line and don't support it anymore.
