I agree with twall. I just built an offset mower and have already had two offers for me to build more. However, the price I would have to charge just to break even would get pretty close to the cost of a Swisher. Now I do think there could be some money in refurbishing older mowers, but I think it would have to start out almost as a hobby doing one or two at a time, and then the profit margin would be slim at best.
