Auto Fish Feeder

Hey Guys,
  I'm in the market for an affordable, dependable, automatic fish feeder.  Any suggestions?  I need something to feed the little monsters during my work day and vacations.  Any help would be greatly appreciated!!

Thanks,
Trish

Except for the clownfish babies, I feed the fish only once/day and often skip days.

For vacation I usually don't feed, unless I'm gone for more than 4 days and then I have an experienced hobbyist come over every 3-4 days to check my tanks and feed. On our recent unexpected 8 day long trip away, we were lucky that my son would be here to feed the babies. He also fed the rest of the fish, but this meant that he slightly overfed the rest of the tanks. It's not his fault and it didn't do any real harm except for a nuisance algae bloom in one tank.

Women are awesome at feeding and mothering. But when it comes to reef fish, leaving them without food for a while actually helps them do better. Feed a little more for a few days before leaving on a vacation of 4-5 days and you will be surprised at how good everything looks upon your return.

On longer vacations, no price can be put on an experienced hobbyist that comes by every 3-4 days to feed and more importantly to check on everything. Many a disaster has happened because an inexperienced person was "watching" the tank.

I use the Ehiem Fish Feeder and it works great. You can program it to feed up to 4 times per day and it has good control over how much food is dispensed. I've been using it for over 2 years without any problems and it runs on batteries so power outages are not an issue.
