I discovered today the motor on a feeder has gone out. Digital timer still works, but I couldn't get it to spin at all. So, I need to buy a new one. Is one as good as another or is one better than them all. Its only a couple years old. Figured it'd last longer than that. I saw online moultrie had one with a built in varmint guard and I kinda like that since the coons climb up and spin it to get corn out. Anyone familiar with it? Any suggestions for a replacement?
