I am going to get this one fixed up but I already have the urge to get another so we will see. Seems like a pair is the way to go. If I go too far the wife isn't going to like it lol.
Oh, a pair is just the beginning. You need one of the 19" models for tight spaces, a self-propelled model for hills, an older "D" engine model that is very lightweight when you want the easiest pushing. And then you need backups.
