So I installed this 40' cable, the one from Best Buy I had posted above, and wanted to report back that it works great http://www.bestbuy.c...51#tab=overview Hole in the floor + knife slit worked well, no giant hole The best guy cable is wide, but it's actually fairly flexible. Easy to route and hang across the basement ceiling. No complaints at all. No picture or sound issues. With free shipping it was cheaper than monoprice. Good deal!
