I've in the past ran a site that started with tens, then hundreds of megabits, then gigabits of traffic, and have found two good options:
1. http://www.fdcservers.net/
FDCservers has had great support. They are absolutely the cheapest per-megabit in North America, with rates of <$150 for 100Mbps, which you can easily push with even a mediocre server. Their plans also don't require you to build or buy your own servers, which is great.
2. http://www.leaseweb.com/
In Europe, you can look into Leaseweb. Based in Amsterdam, they have great rates (<$150 too for 100Mbps) for their dedicated servers, slightly worse support than FDCservers, but still pretty good service. They're based in Amsterdam, and have pretty decent North American data transfer rates despite their location.
