Hello all you Bobcatters, I am getting ready to purchase a used Bobcat. I want to use it to finish a new house (rolling scaffold, landscaping and also snow removal). I looked at a 743B diesel that was very nice for the age, I hesitated and it was gone. The dealer called and said he had a 642B coming in and thought it was a good unit for the money ($6500.00) It is a gas 89 model year. I would like to know your opinions on this machine as far as engine reliability, pump, drive, etc. I realize that it is used, but, I want a machine that was not born with a multitude of issues. Any insite would be appreciated. Thanks, Randy
