Even Monster has basic cable in bulk that's affordable. But get good connectors. Banana plugs are really convenient, and there's certainly no difference in sound quality--or spade lugs are fine. If you are going to run the cable under a rug, there's special flat stuff that doesn't leave a bump in the rug. 14-gauge is fine unless the run is really long.
