Well, unmetered for cheap is usually two words you don't want to hear. You might be able to snag a 10mbit unmetered service from someplace like theplanet/servermatirx for 200 a month, but its going to be a pos server.
Yes, unmetered servers are unmetered, but they also almost always have a tight bottleneck. I've yet to find a decent one with higher than 10mb/sec transfer speed.
