Looking for an Easy to Use Edger?

I mow a very large lawn. By the time I am done I am having a hard time getting to the edging around fence, house, and driveway. I have an electric edger and it is a hassle to even get it to the far-off places that need edged.

Can anyone recommend an edger that is easy to use? I am willing to spend some money on this, because I don't want to hire someone else to take care of my lawn. What is a good brand of edger that isn't difficult to change the line on and can take on a large yard?
