New installation - Self/intsaller & Moco filter?

I'll be switching from Telus to Shaw internet 300. After giving Shaw tech support my exact address, I was told I could just P/U the modem from retail shop and do self installation (installer option is also available to me FOC). On the other Shaw thread someone mentioned the Technicolor XB6 Avanced Modem/Router with Moca filter, however I was told by tech support that only installer could do the Moca filter. Am I correct that its better to let the installer do the setup with Moca filter and request for the Technicolor XB6 Avanced Modem/Router? Thanks.
