Looks like they are with kingcomp aka http://www.fdcservers.net or that is whom there privider is with. As far as I know kingcomp use cogent and cogent only. Things could have changed since last I looked however.
Yeah if your on cogent you can get away with that cheap on a 10 megbit line or what not but then you also have to see if that line is being shared with like 200 other servers or jsut a few or so on. So yes you can get away with that much bandwidth for that little but be careful because the speed may not be all that great. At that price though they probly are not making much profit for themselves. Also you sacrafice lots of service most likely and are not even dealing with a real pro but maybe a 13-15 year old kid.
