I bought a set (component+audio, toslink, ethernet, speaker wire) from monoprice, went with the cheapest grade on everything, and was amazed to find the cables and connectors are at least the same quality as anything costing 10x from a retail store.
Especially the optical cables: the monoprice toslink has a decent thickness to the shield around the fiber optic core. My other toslink cable is much thinner, and I'm afraid I'll break the fiber every time I have to move it.
