I have spent about 2 hrs. searching and reading on this topic. I have learned alot, but it boils down to this: I can purchase a 737 w/54" deck for $200 more than the 727 w/54" deck. Both have the 23 hp Kaw. Is it worth the money? I am concerned about the vertical engine on the 727 vs. the horizontal on the 737. From what I have read there is mixed opinion on that. What is a man to do? Thanks.
