Hey I was thinking of getting a different feeder as well. The one I'm looking at is the Lifegard Automatic Fish Feeder.

Here are some of the features:

1. feeds 1-4 times per day automatically
2. feeds flakes or pellets
3. Attaches to aquariums with frames up to 1"
4. Silent, dependable electric motor 115volts, 2.7 watt
5. no batteries to fail or replace

Can add optional hopper to store up to 4months of food.

I think I might get it.
