Thinking of switching to direct tv. $40.00 increase may have been the last straw.Can i use the same cable's that are in the house now from tw.? Do i need a phone line? If i switch it looks like i will save about $60.00 the 1st year and about $35.00 the 2nd. Are there any other thing's i should look for if i decide to switch?thanks for any suggestions.
