I goto Monoprice for all my cabling needs. This order happened to be for my CCIE study pod I was building. I could have built my own, but their prices and quality make it silly to do so. SHOP MONOPRICE.COM
PROS: Fast service, low prices, and high quality products.
Comapring to the other products you are selling, this item is very low on quality. I am using these in my Home CISCO lab for trunking between switches. Its very difficult to remove the cable once you plug it in to a port. The RJ45 jack is very poor quality.
