An electric fence question.

[Elsbet]

I've been doing some searches today on electric fence chargers. Basically, I need something to fence in along our roadside edge. My animals are all contained already, but we are having wicked problems with neighborhood dogs in the past couple of weeks- much worse than usual, since I asked a neighbor to please keep her dogs off my lawn (pitbull/boxers, and MEAN, unsocialized ones at that).
We have MAYBE 300 feet of road frontage, and another 50 feet to go back along the side lawn. The other side of our property is bounded by our neighbor's old cattle fence, and he said I'm welcome to attach my fencing to it. It's not electric, so I'd use an insulating clip between the two.
So my question is, is there a super small (read: cheap- DH is dealing with lay offs every few weeks, so money is quite tight) fence charger that would do a small area like that, and still be a decent deterrent to dogs? And can I hook it up so that it doesn't have to have a complete circuit, but that I could basically make an L shaped fence?

You bet you can make in a L shape my is in the shape of a horse shoe never to meet on the ends fencers that this do NOT have to make a complete circuit that is why the ground is there. And I just checked the end of my horse shoe fence just yesterday and ALL 5 lights lit up on those testers at 5,000 and blinking just about as bright as the first light blinked.

It doesnt take a lot of power to deter dogs, but buy as strong a charger as you can, just to avoid finding out the "cheapest" one isnt good enough.

I once bought a $30 charger to "save money" and ended up buying a GOOD one a couple of months later when it quit on me

Tractor Supply has one for $89 in the paper. it will put out a charge for three miles. I thought of an electric fence but I am now going with a chain link. It will be tacked on the inside of a board fence. The electric is good but, not for me yet.
