I have looked at the residential mowers and am not impressed with many of them. The best thing I have seen is the Cub Cadet 2000 series mowers. Forget the ztrs in that price range. They run in the mid $3000s. I am wondering if I wouldn't be better of with a used commercial machine. If so where do I find them, what should I look out for. I have 3/4 of an acre and I live in Raleigh, NC.
