In Romania competition + initial lack of regulation and lucky timing led to incredible speed + cost (my ISP just launched 10Gbps fiberlink for 10EUR/mo; 2.5Gbps is 9EUR/mo, 1Gbps is 8EUR/mo, 500Mbps is 6EUR/mo and the slowest option). That said, I think we just got incredibly lucky and I wouldn't advocate "lack of regulation" in general.
