I've often noticed monoprice has three different price "levels" of cables. I've bought the cheapest and the mid-grade of component and audio cables, and couldn't tell the difference in signal (not that I would have expected to be able to distinguish).

Their prices are so low that you can reward yourself with the mid-grade stuff and still feel like you got a screaming deal all in. I'm normally annoyed to have to pay sales tax living in the same state as the seller, but with monoprice I don't care. What really gets me is when I go into a place like Best Buy, and see them retailing a cable for $30 that monoprice sells for $7!
