Greg, you stated that the ADF-75DP from Outdoor For Less possible uses the F-24DT timer, and that the ones with the new PT-6 would be a much wiser choice. Since I was also looking at that feeder, what are the advantages of the PT-6 over the older F-24DT. I have heard good and bad stories on the older ADF-75DP, is it now a better unit with the PT-6. Has anything else changed on this unit besides the timer? Dont want to sound picky but I would like a worry free feeder is possible.
