Lyngsat seems to be messed up at the moment. It's not showing any of the DC2 sub channels that I get from there.
It will work, you will need a subscription to get the subscription channels. This will also unlock some other free channels like American Life TV.
Some providers offer the G4R Ku (X4) only package for around $14 per month (with annual sub). It includes TVLand, Golf Channel, Fox Movie, Outdoor Life, and some other goodies. The 920 and 922 models are capable of voltage controlled polarity switching, which means if you get a standard LNB with 10750 LOF then you're good to go.
Cheap way to go is fixed dish on X4 (Ku side of G4R) and a 920. One coax would do it all, no extra motor or polarotor controls needed.
Better way to go is a 922 because it can do the SCPC.
