Hey Chemdawg the above mentioned feeders are really great , first rate. If you are on a tight budget, just look at Academy/Dick's, you can pick up a Moultrie, etc for around $300 ON SALE. The timers are good, simple and fairly sturdy. I bought 2 of them 5 years ago and they they are still chugging. I have replaced batteries but no other issues.
Good luck on your pig hunting!!!
