You're asking for far too much from a regular shared account I believe, 50gb/150gb regular hosting with unlimited features + CentovaCast/ShoutCast... Either you're planning to pay a fortune or you aren't aware of what providing such services really costs.
Sorry, Won't use a VPS Never i absolutely hate them in general there so unstable if I'm going to get anything would be a Dedicated server or a Shared Hosting account.
I need it with dedicated IP Address as i can supply my own ssl certificate. Centova cast i am able to supply as well as it is the one which only has 1 account possible which i would need installing onto the server for me. The hosting specs a shared hosting account should be able to supply as I've had this many times before without a problem. The hosting package i am looking at paying roughly £15 - £20 a month with out centova and ssl certificate as i already have these present ready to be setup. So yeah
Hmmm.. on the contrary more people are actually trying out vps since it has a lot of advantages over shared hosting since its almost like a dedicated one but for a much cheaper cost. And the people you were talking about who doesn't like it probably just got unlucky with the provider they chose.. But of course in the end, its all up to you whether you want to try it or not.
