What do you mean by rated?
From what I've seen you download actual files at around 10% of the connection speed...
I've got a 28MB connection and average 2.5 - 2.8 MB/s download speeds
when I had AT&T I had the "elite" package which was $35 a month for like... 6 or 7 MB connection...
now I switched to Road Runner and started at 7MB... and they've upgraded their plans over time and now I'm at 28MB for the same price.. I think it's something around $50 a month... I dunno it's all on one bill so I dunno what each costs...
