I agree easy call. If you don't call this at these stakes you are giving up considerable EV. Now things change based on opponent, but there aren't very many oppenents out there that should be a fold consideration. Most players at these stakes would never push with a 4 on the flop. They would wait until turn or river. On the other hand there are a ton of crazies that will push with a weaker ace, draw, or some silly cards. You will see a 4 from time to time but that is no reason to fold.
