There are lots of places that claim unlimited bandwidth or space. Its all a lie. Even places that offer you 5-10 gigs of space, or 200 gigs of transfer a month, or anything like that. They're lying about it, plain and simple. Their goal is to get people to sign up for their service and not use nearly the space they're "allowed." They over sell their space and bandwidth by quite a bit, and if you start using too much of it they'll yank your hosting.
Go to nearlyfreespeech.net. They price realistically, they only charge you for what you use. Unfortunately, if you really do have 1500 megs of stuff it will cost you more. Their rates are awesome: $0.01 per month per megabyte of storage, and $0.01 per month per 10 megs of transfer. For almost anyone that is a great deal, I suppose unless you're hosting a bunch of videos or something.
