I do. (Frontier FIOS, Southern California) I pay for 150Mb/s up/down and always get those speeds, even at peak times. (I don't get the full speed on my wireless devices, 100BaseT ethernet devices, or network over USB 2.0 devices) I pay $90-$95 per month. (this is a residential ISP, not a commercial one. Commercial ISPs typically have a SLA and "up to" is well defined in the contract if it's applicable at all.)
