I have both and agree.For just KU I really like the Extreme II.I use that for G10RIceberg said:C-Band would be the BSC421 LNB that DMSI sells (in my opinion)
KU would be either the Invacom Quad QPH031 (does circular & linear on same LNB) or if you dont want to drop money on that and just want KU, Sadoun has a couple good LNB's
