We need to pick up one of these, probably this weekend. What do you like? Gas? Cordless? corded? We have a typical suburban lot, not tiny but not big either, 40x112 ish. I will use it a bit and DH will likely use it more. I'd rather not get a gas, for environmental reasons and they're just too noisy. Are the cordless ones powerful enough with enough of a charge? Is the corded ones annoying with the cord everywhere? What do you have and what do you/don't you like about them? thanks!
