I know a guy selling his landscaping equipment. He has been the only owner and says he maintained everything and that they are in good condition. I'm thinking about buying: 1. 36" Great Dane. 300 Hours. 2 years old. $2500 2. 52" Great Dane. 3-3 1/2 years old. 575 Hours. $3500 Are these good prices? Would you buy neither, one, or both? Any advice would be helpful. Thanks!
