Solar-powered punch-button calculators

I still have the TI-82 graphing calculator that I first got for calculus in high school, but even after replacing the watch cell battery, it appears to be dead and gone.

Today I finally broke down and ordered two solar-powered scientific calculators, one for the house and one for the lab. I'm getting tired of walking over to my laptop to punch keys whenever I need to do calculations at work.
