My first fixed dish was aimed at 123. Then I added a LNB for 119 (NASA) and 129 for whitesprings (which is also gone now). I loved that setup.
Did exactly the same thing myself. It was an excellent combination of LNBs/channels.
I was thinking about this the other day. I know that it took me a while to finally take the plunge into FTA, and what finally made my mind up was entirely due to seeing what was available on 123 at the time (3 years ago). While I am hopelessly addicted to this so-called hobby and have no regrets, I really do wonder, with what there is available now and how it is so spread out it among the various satellites, whether I would now have taken that first step into FTA.
