I've used nothing but a battery powered mower for the last 20 years now and love it. It gives all the benefits of electric but no cord. There is no gas and oil to fiddle with. There are two appliances we won't do without- my battery mower and my wife's BOB. Just kidding about BOB.
I highly recommend the battery powered mower. They're a little more expensive but you save all that gas, oil and inconvenience. I have a huge yard and the charge usually let's me cut the whole thing.
