In my opinion the monster cables are worth the extra money if your budget allows. They use excellent wire for low signal loss and have good shielding for less interference. As you have found out if you buy them at your local dealer it will not be cheap. Try looking at the price comparison sites on the internet for better deals. Even if you don't decide on monster, I would recommend going with something other than those "out of the box cables!" AR, Phoenix Gold, etc..
