Good automatic feeders

OK, I have a ravenous beast in the house and I can't take her waking me up to feed her. At 3 am she'll start making all sorts of noise to try and get me up, stick her paw in my face, the works. So, can anyone recommend a good electronic feeder? I'll still do the morning and evening feedings myself, but I figure I can get two of them (one for each of my cats) and have them set to give an afternoon and a midnight snack. That way, maybe she won't be so impatient. So, again, can anyone recommend an electronic feeder that will serve at least 2 meals? Also, she is quite the Houdini, so it has to be sturdy enough that she can't pry the top off or anything . . . .

Boy does this sound familiar! I too have a ravenous beast who forced me to get her an automatic feeder I have the Cat Mate C50, which can serve up to 5 meals & has two little ice packs underneath in case you're feeding canned food. I've seen them in stores for $50+; mine came from e-Bay for a more reasonable $30. If you go to their site & search "automatic cat feeder" you'll get tons of results, the Cat Mate included.
