Lamco are great feeders. If you don't have that kind of coin, the new All Seasons is an economical option in a timed protein feeder. Both offer galvanized hoppers for long term rust resistance.
As to the actual pellet, lots of good choices. Just depends on what is available locally. I like Lyssey & Eckles myself, but Purina, Record Rack and others offer good blends too. Just check out the trace mineral packages. Not all proteins are created equal.
