And just the opposite for me! My first D* install was relatively simple, two basic receivers (many years ago) and the installer even got into my crawl space (1 story ranch house) so that I didn't have any wires visible anywhere on my house.
E* was a different story, and a little more complicated. We upgraded to a split level house, and went for the 4 receiver (1HD, 1DVR, 1SD). I wanted the DVR unit an upper bedroom, and the TV2 output to a downstairs office.
First off, the guys were not very confident in their installation, and they fed me false information about my programming, and HD with the then current 811. Thanks to SatelliteGuys, I knew what I was doing. I showed them where I wanted my DVR, and I left them alone for about 20 minutes.
They mounted the dish behind my chimney on a very tall roof, and I was quite happy because it wasn't visible from any side of the house. My dream was crushed when I walked out front and saw that they had installed the DVR on the front outside wall of my house, and I now had a black dual coax cable running parallel along my white vinyl siding. Yes, that's right, they drilled a hole in my siding, instead of the other wall (corner room) which would have been invisible. I was pissed.
To this day, I love DISH's service, but my installation has scarred my house. I don't even know how to patch vinyl siding so that I could move the cable myself. Great service, scary installations...
