Can Anyone Recommend A Good File Host?

[Xtro]

Involved with setting up a new ebook press for a writers' group, and rather than run around making mistakes I was wondering if anyone here knew of a good file host - to store ebook reader files, and provide download accountability without creating hassles with the likes of PayPal, etc?

 

Intention is to use several affiliate-style outlets, but we're looking for something other than hosting the files ourselves due to bandwidth limitations on the site we have at the moment.
