I tried many webhost sites, but non of them is what I expected, at least not if you don't want to become a Premium Member and pay for the services.
Of all webhost sites I prefer Megaupload, as they have a very stable connection and allow to send large files, without the need to RAR them in many smaller files.
Secondly, if you pay a small some of money, you become a Premium member, with VIP handling. Once in a while I do that if I want to Up- or Download large quantities.
It would be nice if other members would also write about their experience with Webhost sites.
