If something goes wrong with DiSH, like some of my channels "drop off" (rare), their customer service people always know what to do to get me back on track. The only other issue is when the receiver breaks down, and they usually have one shipped to arrive faster than a cable repairman.
My main gripe is the price. I miss my old C-band and amazingly cheap a la carte programming. I just wish TCM and the Fox Movie Channel would go HD. I would have plenty to watch then.
