Which would you get: a cordless electric mower or an electric reel mower?

Question:I've been looking at both and most say the same basic things except that the reel ones you can use longer because of better batteries and because they will mow without the power too. Has anyone used both? Has anyone used them on Saint Augustine grass? We have a 4200 square foot yard. I'm looking to take over mowing duties from my husband and I want something other than a gas mower. I'm also kind of wary of the $300 price tag. Can you find them cheaper?

Answers:
the only advantage of cordless mower is you cannot accidentally cross over the line ,disadvantage is the time limit of the battery and you need extra battery and fast charger to,on the other hand the electric mower is cheaper but you might accidentally run over the line and get electricuted,the other one is manual mower that you push way cheaper and more excercise good luck
