I originally subbed in Dec 1998. Stayed through Feb 2003 (almost 5 years), when my SO and I moved in together, and switched to cable. (It was physically easier, and they had a $25 x 16 months promo for Dish-switchers.)
After we got an HDTV/Home Theater setup in Jan of this year, she signed up as a new Dish customer (from my recommendation, BTW :shocked ).
My old receivers, a 3000, 3700, 4700, and 2700, as well as our recent 311, were all rock-solid compared to the tenuous 811. (Even the 510 has occasional bouts of flakiness, but nothing major.) I hope the soon-to-arrive 721 behaves itself.
I think maybe Dish grew too big too fast. It really is apparent when you leave for a while, and come back. I'm hoping they get their act together before our commitment is up. I'd like to stay, but we will have no second thoughts about switching. Brand loyalty is not an issue. (I find it ridiculous to become emotionally attached to a brand or company.) Whichever company provides the best value gets and/or keeps our business. (That includes cable and Voom, not just E and D.)
