I know how you feel!I started out with a 36" motorized ku system and it wasn't long before i had to get the c-band.I believe the ws1870p is the ws international special! cheap price and many here have bought one with good results.If you live in a area that has a habit of having alot of very high winds i would get a higher quality dish.A 6 footer when set up correctly will get you alot of what the c-band can offer but not all.Bigger will help with some of the low powered tps and some S2 signals.To cover max amount of the arc i would get a 24" actuator.I don't think the 5701 will power the actuator so you will need a V or G box.I use ribbon cable to connect from the receiver/v-box,actuator and LNB but at 1$ plus a foot you can use Rg6u with some cheaper multi wire cable.If your planning on using this new dish just for the c-band there are a few good single band LNB's you can get from the gold sponsors.If you want to do both ku and c on this dish the DMX 741 is a good choice.Your present receiver will work on getting both ku and c from a satellite but dont know if you can get s2 signals and most likely no 4.2.2 transmissions.See my signature for my 6 footer setup.
