cordless electric mower

I am looking for suggestions for a rechargeable, cordless electric mower for a very small city lot. Right now I use a human-powered reel mower, but occasionally it rains so much that the grass grows too long before I can get to it, and I think the electric one would be a good backup. Any suggestions as to brand, features, etc.? I tried out my neighbor's one last summer, and really liked it, but he has moved and I don't remember what it was.

Thanks.
