I completely agree regarding the overhang. I went for a little GX100 on my 14". I think I'd scrape the bolts down the side before I scraped the motor housing, there is virtually no overhang. But you pay a pretty penny for the GX100. I wouldn't trade my Honda, but I have to concede that the FJ is much better value.
I don't collect mowers. I just require Multiple Mowing Solutions™.
