torque wrench accuracy

Where can i get a torque wrench?

Where can i find a decent little torque wrench? I dont want to, and physically cant afford a $99+ wrench that will be used only once and a while. But i need one for when im tinkering with my guns or adding new scopes (got a barrel coming for my 10/22 and i need to get the correct torque so that i can hopefully get the most out of the barrels accuracy.)
I need to buy one because i live an hours drive from any store that sells/rents them and i only get to town one MAYBE two times a month. And thats what im afraid of most is overtightening so im trying to find a wrench so i know i am not going to ruin anything.

If they have a Harbor Freight in your area, there was one advertised last week for $19. Here is a link to the ad showing it.
