Don't know what everyone is using but I'm always looking for a cheaper post. Found this one at Menards for $.99. Five foot plastic garden stake. I plan on drilling a starter hole for these rather than pound them much. My ground has turned to concrete. Probably don't even need a insulator but using one anyway. Although flimsy I will also be trying a 5' piece of 3/4" pvc to see how they hold up. I tried some sunn hemp for screening but need a whole field of it to keep the deer from destroying it.
