if you want the real deal satellite tv experience then get C-Band or Ku-Band [or both]. the equipment is pretty pricey though & you'll need a good deal of room for a big dish if you want to be able to access the most satellites available to you and get the best possible signal.. but with this once you've put all the money down on everything you can get what are called "cams" and be able to receive programming for free.
normally sat dealers won't tell you about this if you're just asking questions, but if you're actually going to be buying the equipment ask them about it and they'll help you out then. it's just a bit hush hush especially in the USA.
another cool thing about C/Ku-Band though is you can pull in pre-air streams[meaning you can see programming like a week before regular sat/cable subscribers get em] as well as you can receive 1st generation broadcasts, unlike the 2nd generation "compressed[re-encoded]" broadcasts that stuff like dtv, dishnet, digi-cable, cable, etc use.. so you'd have higher resolutions & bitrates of channels so they'll look alot better then regular sat/cable.
but yeah, if you can afford this then you're good to go and going to get the best tv experience possible.
