How long will you be gone? Fish can go quite a while without food. I had a feeder not work while I was on vacation for two weeks, and the fish were fine.
If you want to get a feeder, the Eheim is probably the best, and the easiest for controlling the amount of food dispensed. You have to be careful not to overfeed.
