I too am switching from TWC - actually getting E* installed today, so I can't yet comment on PQ. But I figure for less $ I get more channels, as well as locals, AND the OSG AND the DVR. And with the DHA, no commitment. I hope I don't have to author one those horror stories about the "installer from hell", and the sequel "csr from hell". So far though, E*'s CSRs and techs have politely answered any questions I've had. Maybe 'cause I'm still a new customer.
On a side note, since I'm really new, and still trying to get up to speed, I've found that the information here is good, even if a lot still goes over my head. Maybe after I've had E* for a month or two all of the system's potential might be more intriguing. That's my $0.02.
