I'm connected by cable modem to Comcast. I', paying $52/mo for 23 ms Ping, 23 mbs download and 4 mbs upload speeds, this according to www.speedtest.net, and includes $7.99/mo modem rental. That modem is a really nice wireless N model. I'm satisfied with the cost for the pertformance.
I am using cable to connect. Paying for 28 Mbps, but only usually get around 12 I am not even sure why either. I know they throttle during peak hours (it's supposed to be 14 around peak hours, and 28 every other time of course), but I just get even less during that time.
