Anyone have experience with these? I have a project that will involve installing approximately 500 t posts over the course of next year and possibly into the following year. It is a project with several phases of fencing going in, so it won't be done all at once. We could hand drive them, but that doesn't sound too fun to me given the number of posts. Normally I would rent in this situation, but since it is not going to be done all at once, the rental cost will likely exceed the purchase cost of a new one or come close enough to be worth buying one. I have seen them range from about $500 to $1,800. These are 10 foot posts, so will have to install them from a ladder. Machine weight may be an issue as the biggest ones are like 45 lbs.
