Hey, Mark, we have the same nifty image on our posts! Hooray for moderators who did this. It's cool. I should find a pic of a Polk speaker to replace it, tho, I guess. Be loyal to "my" company...
Anyway, I got the Lowe's Task Force 20" corded electric. I mow a lawn that is maybe a quarter acre or a little more, front and back. Nothing's more than 60' from the outlet, and if you keep the outlet to your back when you mow you never have an issue with the cord.
I was worried that build quality would be crappy, but the thing is solid and fairly heavy duty. I explored the battery ones, the Neutons and Black & Deckers, and even tho my town has some sort of agreement with Neuton to give a discount on them, I found them to be sort of cheap (but very expensive, even with the discount) and the batteries got bad reviews as too expensive and too difficult to keep charged. The lower end B&D corded ones seemed like toys, more like my B&D weed whacker than a real mower. And the 20" blade of the Task Force really helps.
Powers thru some thick grass, too, with no apparent problem. Like I said, it's very much like "vacuuming" my yard.
I'm actually giddy about it, and wish the grass would hurry up and grow so I can mow again! (Be careful what you wish for!)
