Westclox Travelmate Folding Travel Alarm Clock, Black 47508
I looked at a number of different travel alarms and found that many are flimsy, and I wondered how long they'd hold up (even an LL Bean one I saw didn't look that great).  Since this one was inexpensive and had good reviews I decided to give it a shot.  I've had it for about a year and it works great.  The price was right and it's very reliable.  I highly recommend it for the budget-minded shopper.
