Do you want to host a new site or a old existing site. My personal suggestion is that if you are hosting a new site than start with the smallest package. Or, if you want to host an old existing sites provide your site's statistical details so that the host can offer you the exact package. If you buy the biggest package and hosting a new site there will be no use of 300 GB space and 1000 GB bandwidth (fox example) if you are starting a new site. Your money will be wasted. As a representative of a Webhost it my duty not only to promote our host but also to provide guidance to the prospective clients. Why don't you register a domain name in namecheap.com or in godaddy.com. If you don't like a host you will just need to change your nameservers of the new host very easily. You won't face the hassle of transferring domain if you do that.
