I agree totally with SHARYNF.
Here's the link to the big orange store. $63 for a 500' spool. I know you need 1/5 that, but they don't say what the price per foot is, but I'm guessing around 25¢/ft. Although RG-59 is less expensive, go with the RG-6. Also buy the best crimpers you can afford, and the crimp-on "F" connectors. I kind of agree BNC would be better, but more expensive and harder to find.
And thanks for pointing out that "link" chain icon. As you can see, I've used it a bunch.
