Component Video Cables

[mzo0163]

Right now Im running 6 year old top of the line monster component video cables from my high def sat box and dvd player to a Pioneer Elite projection. The cables seem to be going bad because there are subtle thin lines that go through the screen. When I wiggle the cables on the back of the TV the lines go away. Im assuming that I need to replace the video cables for both the sat box and the dvd player because problem happens for both. Im not looking buy monster cable brand because I think theyre a rip off so Im wondering where I can find high quality inexpensive cables online. Does anyone know of any good sites to buy from. Thanks.
