I bundled my DISH with Frontier last February (see signature). I couldn't be happier and let me tell you why.
1. Customer Service. To do anything, you must call Frontier and they'll get ahold of DISH. The best part, Frontier has the call back feature where they call you back when it's your "turn". This way your phone doesn't stick to your ear after 45 minutes. Also, they all are American. Frontier and DISH do a three way call and you are always speaking with an english speaker.
2. The cost savings. Frontier ran a promotion that you get the 250 for the remainder of 2009 for $9.99/mo. Of course I have my DVR fees, extra receiver fee, HD fee, etc. But still with pretty much the best package (minus HBO and Showtime), I'm paying a total of just under $60. BTW, that includes the digital landline with caller ID, three way calling, voicemail, call waiting, and 100 long distance minutes (never use, but what the hay).
Our family is stoked about this partnership and look forward to continuing it in the future. This is a WIN, WIN for DISH.
