Gepco is sold predominately in 1000 ft EZ pull boxes and spools. The major consumer is pro A/V houses that do install work. I worked for a long time for a pro audio company here in town and they have every color of it under the sun. They buy such quantities that it becomes rather inexpensive. Check these places. Also ask if they have scrap, all my patch cables are made from remnants and that is sold for pennies, if not free. Often times you can get a 20-25' remnant from a big pull with a bunch of colors in it. I may have a few 8 pair bundles here soon from an install here at work, I'll keep all informed!
As for the Belden Equiv.... let me go look...
Belden 8451 ids the EZ strip like Gepco 61801EZ Tough Jacket, Foil shield, bare drain wire and a pair of conductors (red and black)
Lately I have been using a little Belden 9452, it is the same diameter, has a little softer jacket, more flexible and contains; jacket, Foil, drain then the pair (red/black) conductors are wrapped in cloth. The cloth can be torn by hand and permits easier flexing of cable. The signal pair seems to made of thinner gauge wire but having the same overall gauge making it more flexible also. The advantage is flexibility the disadvantage is that the rework time is longer because there is more steps involved in termination. The 61801/8451 is soooo easy to work that I don't even recommend strippers, just score the jacket snap it in either direction pull, shuck the foil and do the same for the signal wires. I can have a chunk stripped and tinned in seconds.
It's damn good wire, I have used it under radio transmitters in broadcast studios and never had a problem with RFI as long as the signal paths are grounded properly. it does not have "bling status" but "bling" for me is worry free operation, low capacitance, and a 100% foil shield
