The product I showed earlier I got from this site :
http://www.mccartenco.com/products/wcpd/index-1785_1112.html That is the kit I got, it consists of 20 6' sections and is $500. You can get smaller kits with less sections but for me I have a couple of guys who are pretty rough on the tools so I stocked up on them. They have different thicknesses .159", 1\4" and 5\16" The smallest ones are a little harder to keep the tip up above things in the ceiling when you are working with more than 1 section, the 1\4" are the ones I prefer, and the thickest ones don't have the flexibility to pull out of tight spaces too easily. I definitely recommend the 1\4".
I said earlier that I stocked up as I have a couple of animal tool destroyers working with me and they have yet to damage one of these so I am happy with the durability.
I havn't worked out of a van for about 2 years but when I did we had a kit that came with a PVC holder with a cap that you can just lay on the ground on the side of your van. Also when running thru cable trays or thru a J-hook path the basket attachment is the key to keeping your cables from interweaving with the existing cables. I am speaking from a tele\data standpoint and i'm sure some of my situations don't apply to you sparky's. But when I was wiring my house for data, phone and TV I used them and they made life real easy trying to locate things in the attic. I drilled a tiny hole in the ceiling right above my cutout in the wall, pushed a rod up into the attic, then went in the attic and drilled the hole down, pulled the snake up into the attic and back down into the wall with the cables attached to the tip, these things really made my life easier locating the framing members I drilled thru. I have always worked in commercial settings so getting used to the whole solid-ceiling and drilling wood took some getting used to for me but these things definitely helped ease the pain.
