Seakerman,
If you want better quality than Monoprice or BlueJeansCables you can go with Pear cable.
http://www.pearcable.com/
However, remember that a more expensive cable does not always provide better audio and video because you cannot defeat the laws of physics when it comes to electrons.
So what do you get with more expensive cables (1) better quality materials in sehathing and structure, (2) better dielectric and shielding and (3) better connectors: silver plated, gold plated= slightly better conductivity.
Here is one article on high end audio cables :

Here is another vendor that claims to have the "World's Absolute Finest Cable' tm:

Having said all that, I usually buy monoprice cables.
Good Luck,
