Hello,
The little dish is the easy answer and the quality is not too bad as long as you do not have a GIANT TV, then the picture quality is more of an issue. But to be fair the same can be said for FTA. Some channels are great and some I am sure you would not want to watch. If you watch alot of premier channels, Food/Movies/Discovery/Si Fi...... then at this time FTA will not give you what you are looking for. If you like sports then maybe FTA should be considered. Our Super Moderator here ICEBERG recently pointed out a few weeks ago that out of 16 football games DirecTV had, 14 of them could be seen on FTA : )
If you like news, raw news then FTA is a great addition to your entertainment resources, being a C-band owner I am sure I don't have to go into all the feeds available, but the news feeds for me are the number one reason to go FTA, if there is anything happening anywhere in the world usually its on FTA LIVE.
After setting up a FTA system moving from satellite to satellite is as easy as changing channel on the remote (same as C-band). I would say with the weather you have a 90cm or larger dish would be needed, in reflection I guess I am too much of a FTA nut to get a fair and balanced (FOX NEWS and ABC NOW are FTA) opinion, I think you would enjoy KU FTA. I hope this helps slightly with your decision but read as much as you can here and don't rush into anything. With any luck the other members here will chip in with their views and take them all into account before you take the leap, many members here only have KU FTA and an OTA antenna, and they get all the TV they need : ) Nice to have you here at the SatelliteGuys.US forum!
