I've been using only half My Bud - the C- Band analog and digital. I want to install a KU Lnb for FTA. I would like to know whit ch Lnb to get for general viewing: One of the Norsat products ($ 150 approx) OR a cheapo unit ($ 40) OR Scrounge around and find an unwanted BUD that has a KU lnb ($ 0). How critical is Drift? I allready have a scalar ring and rotator - for the C-band and KU lnb, Just missing the KU Lnb.
