Monster Cables are a rip. You basically want to go with good, solid, cables. I got some Accustic Research speaker cable at Best Buy for half the cost of the Monster stuff. You can get even cheaper off the net. Get 14 gauge or so.
I needed to get some really long cable runs for my Benq Projector. At 75' pretty much every A/V cable place would have bankrupted me. I found a great place online
