The 4DTV receiver is prob what you want for the most variety of pay=programming. They are expensive, sometimes deals can be had on craigslist or ebay, buyer beware. I'd want to be sure, if I ever decided to get one for myself, and buy one from NPS or Skyvision, or some other known dealer. This will get you c band, digital and analog signals , if you add ku lnb to your dish-ku digital and analog also. The descrambler is built-in.
There is also the new X4-package that works on one ku satellite, with sev programming packages available from skyvision. A 1m ku dish/lnbf parked on one satellite will get you many channels, No need for dish motor, or wiring into the bigdish system.
