to tell you the truth i wouldnt have a problem renting it to jow homeowner for 450 a day though. What are they really going to hurt? if you damage it from stupidity like break the glass out or roll it over i would have the proper waiver signed/credit card on file/back-up insurance policy to cover. Let it warm up and cool down and other then that i cant see a home owner doing any damage to the machine. thats what a warranty is for right?
