S-Video Cable Recommendations?

I'm looking to run about 60-70 ft worth of S-Video cable in the near future, along with an equally long PC Speaker wire. My concern however is picture quality. I realize that at longer lengths the picture will diminish, and perhaps end up unviewable. So, I need some help.

I was looking over different makes of S-Video cable, and without any actual technical knowledge about the wire, or how it works, I find it difficult to pick out a wire that will work for me.

Can anybody recommend a site that sells S-Video wire that can be used at 60-70ft with good picture?

Thanks in advance.

 

The longest cord I could fine is a 50 ft cable and that's probably because beyond that you will lose too much quality.

 

I've managed to come across 100 FT S-Video cables, but I look at them and wonder.

They're pretty inexpensive, and because of this (along with what I've heard about S-Video) it sounds like it simply wouldn't work. Or would produce a terrible signal.

I'm looking at Monster Cables right now, and they claim to be capable of sending picture across long lengths with great results. I'm thinking that I might be able to get by with 50 ft of S-Video cable if I can run it under the house in a straight line. Otherwise, I might have to skip this idea, and build a media center machine.

 

Have you thought about maybe using s-video breakout connectors, and then using coaxial cables for the distance in between?
I would've thought decent coax would hold the signal better than an s-video cable (probably cheaper, too)
