Tractor Supply has some fencing that I would consider instead of that high priced chain link:

I used the underground fence for a couple of years, but that stuff has drawbacks. Lightning loves it and will fry that little transformer. The dang underground wire breaks a lot. And it doesn't keep all the other dogs, etc, out of your yard.
