@TorrentLover all depends on how you plan on using your seedbox. If you a heavy user, feralhosting or seedboxes.cc may not be for you as they do have a monthly cap.
i've used both in the past, but the download cap bugs me, so i went with an unlimited package, such as wicked servers (tal0ne), depending on the service and the location link, it is amazing. also there is whatbox or seedstuff.
