It is all over the place. The worst part is when you realize reputation is always a trailing indicator the only rational action seems to be to buy the cheapest one and use the saved money for the replacement. Basically, optimize your life around rapid disposal and replacement which makes extra trash and takes extra time versus just having a good quality item you can rely on.
My mower recently started to rust out and I dread buying a replacement. Aside from cheaply replacing poorly designed wheels fairly often I was 100% with this mower. But I can't buy it again because the march forward with redesigns means it is no longer made. Is the new one better? General life experience says, probably not.
