I've got a reel mower just sitting in the garage, but unfortunately I don't use it. You'd probably get a really good workout. I see a neighbour trim his grass often and it looks super.
I came from mowing my parents' lawn with this
to this
My parents' self-propelling one was awesome to use coz there's wasn't much effort involved. The engine would roar and it felt like a mustang of lawn mowers. The current one I have is less "beefy", but it does the job. After work when you're tired, it's a pain to do a chore. But you know if you've got a small lawn and if you need to get some exercise, the latter is a nice in-between.
It's too bad you're set on electric. You should give gas powered ones a try.
