I'd say Ridgehunter is right if you have the terrain he's talking about. I've been eyeing a ZTR for a few years, but still haven't bit on it. My dad bought a John Deere z445 a few years ago, and he loves it. Looks pretty solid, Kawasaki engine, and he got a few extras from the dealer. I really like it, and it would likely be the way I'd lean. I'd go Ridge's way, but my lawn is pretty tame, so other than me crashing it into something or dropping it into the occasional hole, it would have a life of relative ease.
