Unlike the "Big Display" reviewed yesterday, the HR-150LC doesn't try to brag about anything, yet has every right to do so. The display on this is actually huge, and is viewable from almost any angle. Every digit contrasts clearly with the LCD.
Each button feels solid and clicky, so every operation you perform with it is going to feel great, especially if you're using the print feature. It's loud without being obnoxious. The printing mechanism has a weighty feel to it that might cause a lighter calculator to violently shake, but this device is heavy and strong enough to handle it just fine. Even the switches to turn the calculator on or change the floating point are a pleasure to use. It's all very responsive and will make you feel like you can kick math's ass today.

It might seem like I'm biased toward Casio, but that's honestly not the case. It's HP calculators that I tend to get overly excited about*. Yet since I've been collecting, Casio has impressed me every single time.
The HR-150LC can run on four AA batteries or the A/C adapter that came with it. I found this one at a local thrift shop for $6. Casio no longer produces this device, as it has been replaced by the HR-150TMPlus. Unfortunately I couldn't find release years for either device, so my best guess is the HR-150LC came out some time in the 1990s.
