I actually looked at that one, surprisingly you can pick one up cheaper on Amazon (even factoring shipping into the cost). I called a place last week and it's $50 for the weekend, Friday through Monday. Just need to decide whether to get it this weekend or not, might be busy Saturday and don't want to end up spending more than $200 total on the rental, otherwise buying that Harbor Freight one will be easier.
Shit though, if they have that one in town, I could start tomorrow. A few panels up each day would be nice.
Edit: Decided to check Facebook marketplace and Craigslist locally, nothing close by other than people asking almost the new price for used ones (and even most of those are at least an hour away).
