I bot a Simplicity Regent about 4 years ago. I has the 38" cutting deck and a Kohler engine with the Hydro tranny. It's been a very dependable machine. I have an acre to cut with hills that require chains and I bag all my clippings.
So far I've replaced the battery once and I've had one deck bearing go out.
BTW....I would not buy any machine from a big box store.
