I'm using a 20-year-old Sony alarm clock: dual alarms, 1" tall red digits, cheesy radio that I don't use. I just go for the beeping.

I have a new-ish Chumby One, which I use to feed Pandora to my stereo system, which I could just as well use as an alarm clock. It's got a not-unreasonable speaker for an alarm-clock-sized box.
