To Buy Or Not To Buy That Is The Rechargeable Lawnmower Question

You all know that I have become very involved in working in my yard. When I first moved into my house my step dad got me an electric lawn mower. He thought it would be easy for me to handle. I wouldn't have to mess with gas or oil or anything like that.

But now I have graduated from the small electric mower and its time to get one with a little more power and don't want to haul the cord around anymore. But I still don't want to mess with the gas and oil thing. I have found one that is battery powered. I just don't know how well it will work or what kind I should buy.

Have any of you ever used a battery powered lawn mower? Is it worth getting one?
