I'm looking at making my own cables as well.
I'm going with the Canare cable and RCA's with the Paladin 8000 crimp tool and 6429 (I think I have that number right) die.
I'm not going to try and make everything look all boutique, but it will be nice to have A) all my cables look the same and B) have everything the correct length.
I have some old Better Cables stuff that turned out to be exactly what I'm trying to make: Canare cable and ends, and I am very happy with the sound and video they produced.
I'm pretty good with a soldering iron, but everything I've read says crimping is the way to go with coax. Better connection with less chance to screw up.
good luck,
A
