I am severely mechanically challenged, so I was hoping for some help. Which is the better value, do you think? A Gehl 5640 (zero hrs) with hand/foot controls for $26K or A 2004 Bobcat S250 (450 hrs) for $25K....I know the owner and machine has been well taken care of......needs new set of tires There is now a 3rd option......a 2005 Caterpillar 242 with 1,000 hrs....I know the mechanic who helped his friend (I know the friend too) go pick out the machine new. The mechanic has worked on it since day 1....no one else. Has steel tracks that are removable, has enclosed cab with AC/heat, has radio..........26K
