FWIW......
We opted to rent ours. The surge collar was already in place on our patio villa - the prior owners had been renting it - so we just signed up to keep renting it. Our overriding thought was that we don't necessarily intent to own the place long term so we just went with the rental. Less cash outlay up front versus buying......but more expensive over the long haul to lease.
Do whatever seems to make the most sense to you!
