what is absolutely the best set-up a guy could install?
Whatever fills your needs. Can be simple single dish capable of C and Ku to multiple dishes and multiple receivers. But it's best to start small and build up the system so as to gain knowledge along the journey. FTA is not 'plug and play'. A good understanding of how all the components work together is a must. A good starting point may be LNB LO Frequency 101 in the FTA MPEG FAQ'a section of the forum.
Ku band and C band? Whats better?
That's up to you, what are you looking for? NOTE: FTA is NOT an alternative source for subscription channels. To see what you may receive take a look at Mikes
MPEG Central. There is also TheList here on the forum. (link on the top af all pages here)
How do I get the most channels?
By having C and Ku capabilities. Either motorized dishes or a number of fixed dishes, or a combination of motorized and fixed.
A good starting system today is the Geosatpro microHD / Ku dish/LNBF package offered by SatelliteAv(site sponsor, link on top of the page)
Add a motor to it after you 'cut your teeth'. If bitten, add a C band dish.
