Take a look at this new version of the electric shock option.

It is fairly new

If you do try it, let us know how you like it.

I froogled up the Zareba K-9 Electric Fencer for under $30 which seems a
better deal. Aluminum wire looks to be $5US a foot.
I had operated a fencer for horses for years. The expensive units include
weed burning, the ability to burn off a weed in contact with the line. This
happens when they are dry so they do not short out the fenceline when it
gets wet. You may not need the expensive version in your garden.
