If your dish antenna looks like the ones in the photos above (DirecTV Slimline or the 5LNB cluster), I have had good luck with those. I currently have one of each pointed at 87W and 129W. Replaced the stock LNBF assembly with a linear by drilling a hole in the appropriate spot and adding one of
Hyper Casey 's LNB holders with a linear LNBF. I did have another of them for a couple of days in the front yard
* on a temp mount pointed at 67W, with a DishPro tacked to the side for 77W.
If you can find locally an old SuperDish, or even better HughesNet, those work great too. I have one of the Hughes dishes pointed at 97W, with additional LNBs for 101W and 105W.
For multiple dishes, you'll want to look into DiSEqC 4x1 or 8x1 switches, and there are more complicated ways if you want multiple dishes and multiple receivers. But sounds like you'll be happy with one dish into one receiver at least until the bug bites you.
* until Mrs Pepper said no dish antennas in the front yard!
