Haven't used them but during our remodel I wired the house with structured wiring. It has two rg6 lines and a cat5 cable all wrapped together. You can buy all different combinations depending on what you want. I picked mine up from Ritz Camera of all places, it was the cheapest and free shipping.
I've used Black Box products going back to the 60s, and been very happy with them. There are lots of suppliers of multifunction (so-called "structured" cable) distribution cable out there; libertycable is one of the biggies.
