There is a store on eBay located in Montreal called Demo Deals Online that carries Hall Research products. They have the kit for US$214. The going price for the receiver alone (elsewhere) is US$218 plus US$70 shipping. The kit seems to be the best deal.
My poor old Bell Home Hub 2000 seems to be limping under the present load on it.
HDMI over CAT6 usually requires dedicated cables. I doubt it could be shared with the LAN on the Home Hub.
