What uses are there for C-band aside from curiosity? Part of me is still tempted to try and get one one of these days, the smaller the better.
It really depends on whether the hobby fits your style. First off, i don't do pay TV. If you're expecting HBO, etc, buy Dish Network. But, if your like me, who likes watching some of the odd ball channels, who has access to channels that are not designed for main stream.. If you enjoy finding new channels pop up, if you enjoy watching feed channels where you can watch the news anchor chat with the camera guy and hawk a spit before airtime.. These are some of the experiences you have access too. Not to say there aren't some great FTA entertainment channels to watch too, but I often tune to some odd ball channel and leave it there for background noise and i find i learn interesting things, or see interesting things.
That being said, the other family members watch the C/KU TV a lot. My mother in Law is Hispanic, and there is a LOT of FTA Spanish channels, and there are a good number of KID friendly channels. But, the only reason they watch it now, is because i made it VERY user friendly. Being i hooked up so many fixed dishes, i have a large number of channels that can be tuned from 4 different TV's in the home, and can be channel surfed and pulled up instantly. I have an 8' foot fixed, a 10 foot fixed, and a 12' movable for me! The 8 footer would NOT be a good dish for probing. I purposefully have it fixed on a bird that has lots of strong transponders. There are LOTs of Signals the 8 footers CANNOT pull in. the 10 footer pulls in 99% of everything you would want, and my 12 footer pulls in 100%. This should tell you why so many people are telling you anything less than 6' is a waste of time, and i personally think 8 foot should really be the minimum if you want to be happy.
