To lower our monthly cash flow to Comcast I'd like to explore replacing my rental modem (for which we've paid several times over) with our own. Their instructions state in part "...a DOCSIS 3.0 or above modem is required...". OK, there are many 'out there', but to ensure I don't waste my time or money is there a preferred brand/model for me to pursue? We have the 'Triple Play' option with no smart tv's. Thanks folks
