There are different grades of commercial, when I was a youngster (a long time ago) my father was a commercial horticulturalist and used several Honda made machines. They are made to fit most gardens and budgets. I recentlt bought one myself for home use and the experience is very satisfying. The larger machines (petrol/gasoline) will compete with and out perform just about anything else and retain that quiet reliablility. If you're hanging onto it hour after hour each day that quieter smoother running counts for a lot over the years, I had a lot of experience with other brands back in the day, the merry tiller is crude by comparison in my opinion.
