RCA RCD20 Alarm Clock
The RCA RCD20 is one of the least expensive alarm clocks on our list, yet it offers reliable functionality at a price point under $10 from most retailers. There aren't many bells and whistles here, just the basics. The unit itself is pretty small and features a .7" green LED display, an elongated top snooze button for easy accessibility when you're bleary-eyed and half awake, a night-light, and oversized buttons that let you control all of the clock's time and alarm set functions. It's even small enough to fit on any night-stand or toss it into your travel bag to bring it with you when you travel. Stick in a 9V battery to use for backup in case the power goes out; the clock will still keep the correct time and wake you up at your designated alarm time.
