Hello, I visted your office last week and ordered service for my new home. Currently i am renting a DHG 535 modem on a monthly bases from Comcast. I want to purchase a modem from a manufacture of a modem that will perform and produce the same results. Therefore eliminating a monthly charge for the rental of $7.00 per month. Can you recommend where I can find one and suggest a manufacture and model number of a modem that will handle my comcast TV,internet, and phone. I will wait for your to respond. Thanks
