Cheap, but practical
This spring-wound clock was just what I was looking for. It's cheap, relatively sturdy, and it has an alarm loud enough to wake the dead. Be sure that you want a loud alarm if you buy this as an alarm clock. My only qualm with it is that it seems to have a short lifetime: about a year or less. Therefore, I recommend any purchaser to hold on to the included warranty: if the clock goes bust within a year (which it very well might), you can send it in for a new one free of charge. Good for travel, as you don't need to set the time every time you travel somewhere, as I have had to do when the backup battery of my electronic alarm clock ran down, as it inevitably did.
