Narrow your search down to a Toro model 20384 or Honda. It's no surprise to anyone on this forum I'm a big fan of the Toro and feel they are the best, but I would spend a little more on the cast deck and the better drive wheels of the 20384.
I don't have a honda mower and do not know much about them. But I see a lot of people come here because it won't start or something is wrong with the drive.
you should read the homedepot reviews for the one above. all kinds of people complain about the honda and its carb and its drive train.
