These are the feeders we have been using for a number of years on our own fish farm. I think they are as good as you can get for a reason price.
The feeder units are totally automatic and will feed up to 6 times a day and comfortably throw a 6mm pellet 30 yards. These feeders have been very reliable and will help optimise feed conversation rates from pellet to fish weight. 
The timer units have an internal battery that makes it easy to save feeding programs during use. These are stored in a bucket with the battery on a feeding stand to allow easy access to the timer.
The spinner heads have specially designed flaps to prevent wildfowl from stealing your expensive fish food and prevent loss of pellet during high winds.
