You might want to try
CabSpace they are free with no banners or Ads on your site. There is no bandwidth caps. Also unlike a lot of free host you can have as many folders and subfolders. That is something you will run in to with even most ISP's free hosting. I run in to that when I was setting up my site first on my two ISP's hosting. Then on places like tripod and yahoo's hosting. Tripod does not like how many subfolders that iWeb needs. I hope that helps. You might want to goto my site to take a look at what you can do. If so the link is at the end of my posting. And no not trying to Spam.
Have a great day,
