You don't have DTV or Dish or cable either?
If I am correct, you don't get any national channels on FTA, which without the national channels I dubt there is much to see
I have cable but it is only 24 channels or so. Mostly locals with a few nationals like Disney channel for the kids. With the cable modem it is only $3 more a month so why not, it makes the kids happy to watch Disney in their rooms. Also the QAM HD networks are there and even my neighboring DMA's HD locals are there too. Plus I have OTA HD. The HTPC has over 1 gig of storage with a QAM and OTA tuner. Love the HTPC especially for cutting the commercials before I watch the program. We barely have enough time to keep up with the shows available on the HD locals. When I'm bored and want to watch something else, FTA has no issues filling that gap.
So basically I have too much to see as it is.
Maybe my answer isn't zero as I said. I spent $40 on some FTA equipment and $3 X 12 months for cable. $76 this year.
