What is a good price for a homeowner used 2003 or 2004 21" Toro proline 2 cycle BBC. This was used for approx. 1/2 season (4 months) and looks brand new. Has been properly stored since he moved into a condo. I am adding another person, need another 21" and always liked the 2 cycles, but they were not made after I started back in the lawn care. Thanks for any help!
