hey guys im looking at a 14 inch woodchuck with a duetz diesel engine . i think around 2000 model. are these decent? he also has a bandit for sale with a diesel. both air cooled, which i was a little weary of. Are either of these any good? Both have been mechanically checked out and referbed with warantys for 30 days. woodchuck is 10,000 ,the bandit is about 1500.00 more
