Hi All, My first time on this site, great info!! I'm being offered a used power rake for $400, it is a former rental unit. Its about 12 years old. The guy selling it sounds like he's been taking good care of it over the years as he babied it with frequent oil changes. Can anyone tell me if its wise to buy a piece of equipment that has probably seen better days but is at a good price? If it lasts two weeks it will be even with the cost of renting one.
