I'll start with what's good about the Scott 2000-20: it's lightweight and easy to push (I'm 51, female, and if I can push this thing so can you).  My lawn is fairly level and it leaves it with a nice even cut.  I love not having to maintain a gas mower and it's nice to mow without having fuel exhaust in my face.  I can mow early, when it's cool, without disturbing my neighbors.  All in all, I'm pleased with the performance.
