I have a 72" Landpride finish mower that literally has thousands of hours on it with zero problems. It is not even beginning to show any wear on the spindles or any of the wheel bearings. Other than eventually wearing out a belt or a set of blades, I think it is a lifetime unit.
That being said, I bought a Maschio 72" tiller a couple of years ago. I'm really impressed with it's build quality and performance too. If the Maschio finish mowers are anything like their tillers, I don't think you could go wrong with either one.
As far as I'm concerned with LandPride finish mowers, if someone has an issue with one, they must be one of those guys who don't own a grease gun. I'm serious. Other than greasing each fitting every 6 hours or so, I've done nothing to my LandPride except mow, mow, mow. I had a JD brand prior to the LandPride and it was not built nearly as well.
