I am thinking about getting the dish network and thier latest deal is $19.99 per month for America's Top 60 and with free HBO and Showtime and a free DVR. I might get America's Top 120 instead which is $30.99. The deal includes free installation for 4 rooms, local channels, and sirius radio. Is there anything that I should know about before I commit to this deal? Such as how much do the taxes and fees usually come to?
