lovemygreen, the Honda Jarryd is interested in has a GCV135 engine. My record of where each Honda model had been made up to 2010 shows Japan as the sole source of that engine. I don't admire the design of the GCV engines, but I have no issues with their build quality.
Jarryd, mulching quality sounds like a good mower selection criterion. Seems as if you have found a solution.
