I really have good luck @ dslreports.com. The user comments can be very enlightening, even someone who may live in your actual neighborhood can chime in on service experiences. Keep in mind your next door neighbor may have a remarkably different experience based on infrastructure differences to your location/dwelling, as well as different AV equipment. It can all factor in.
Does anyone around Detroit have AT&T U-Verse that can tell me how it works compared to Comcast? Seems like they have some good deals going, just wonder how their internet, phone, and HD TV with DVR work based on people's experience. Thanks.
