No advice about brands, but ...
Here in AZ the local electric utility (SRP) has a "Mowing Down Pollution" event every spring. You bring in your old gas mower, and they give you a certificate for $100 off an electric mower from Home Depot. Home Depot has a presence at the event, and will sell you a new mower on the spot. Last year I got tired of the annual fight with the old mower, went to the tradein event, and drove off with a 20" B&D with grass bag and a 100' extension cord for something like $160.
Been real happy with it, only maintenance is keeping the deck clean and the blade sharp.
You might want to check and see if your local utility company has a similar promotion.
