Do I really need a VPS?
 

I'm sure this gets asked quite frequently, but I'm still rather new to finding the "best" type of hosting option. My forum gets a few hundred visitors a day, at peaks times around 150-200 people are browsing the site at once. Currently we're on a Linode VPS, but it's a friend's server, who I currently pay $40/mo for space, which is starting to become a bit of a burden for me. Would a premium or business shared hosting type package be sufficient?

Thanks,
Mike
