I bought an A1 mister, PTO driven and goes behind a tractor. If you buy a mister thats what I would buy. they seem to be built pretty good. Doesnt seem to scare the deer, they just walk to the other side of the fence. But with us farming and a dog kennel up the road... my deer are pretty use to noise. The mister is pretty quiet though. tractor is much louder. Ill end with this.. whatever you get... youll probably like it, and its better than nothing.
