Don't forget to mention DVB-S2 HDTV on FTA. I watch PBS HD on satellite AMC 21 at 125W. PBS on satellite is frequently different than my local terrestrial broadcast IPTV (Iowa Public Television).
I recently purchased Ku band FTA equipment from Sadoun. Its great fun.
I love

www.lyngsat.com is interesting and more complete but harder to navigate.
www.lyngsat.com includes C band FTA.
