I am looking to start a new company next year and trying to get good Equipment the cheapest way. I found an Exmark 21" with kawasaki for $850, and a toro for $950. which as i was told are almost identical. I found a toro shell/ frame on ebay for $35. Now the questions is if i puchased that and build it with new parts or found one with a bad motor and replaced the motor how much do you think it would cost and would it be a good idea?
